NegativeScreen is a Windows application allowing you to invert your screen colors.
Apart from accessibility matters, this software is especially useful when you are surfing on the internet in a dark room, and the screen is dazzling you.

NegativeScreen was designed to work without impacting the performances and fluidity of your computer.
Unlike the Windows Magnifier, which is also capable of such color inversion, it was specifically designed to be easy and convenient to use.

Different inversion modes are provided, including “smart” modes, allowing blacks and whites inversion, while keeping colors (about) the sames.


Simple Inversion

Smart Inversion




The color inversion takes effect immediately after starting the program.

NegativeScreen comes with a minimal graphic interface in the form of a system tray icon with a context menu.
You can toggle the inversion by clicking the tray icon, and access more features by right clicking it.

Along with these commands, you can also control NegativeScreen only by using hot keys. Read on…


Default hot keys

Win+Alt+H: Halt immediately the program
Win+Alt+N: switch between normal mode and colors inversion mode (Night vision :))

Win+Alt+F1-to-F11: change inversion mode:

F1: standard inversion
F2: smart inversion 1 – theoretical optimal transformation (but ugly desaturated pure colors)
F3: smart inversion 2 – high saturation, good pure colors
F4: smart inversion 3 – overall desaturated, yellows and blues plain bad, actually relaxing and very usable
F5: smart inversion 4 – high saturation, yellows and blues plain bad, actually quite readable
F6: smart inversion 5 – not so readable, good colors. (CMY colors a bit desaturated, still more saturated than normal)
F7: negative sepia
F8: negative gray scale
F9: negative red
F10: red
F11: grayscale

Keep in mind you can always change these defaults by editing the configuration file.



The version 2.0 (and 1.13) introduces a configuration file allowing to tweak almost everything in NegativeScreen.

You can now choose your own hot keys if you don’t like the defaults, and you can even add you own color effects!
This requires some knowledge in color matrices though.
I may add an easy way to build some in a future version…

If the configuration file (negativescreen.conf) is missing, you can use the “Edit Configuration” menu to regenerate the default one.

Should something go wrong after edition (bad hot key…), you can simply delete the configuration file, the internal default configuration will be used.


Windows XP Version


Unfortunately, the Windows Magnification API this application uses, is not available on Windows XP.
Therefore, I’m sorry to tell, there will be no XP compatible version of NegativeScreen.




NegativeScreen is freely available, along with its source code, under GPL license.


Latest binary version (if you don’t know what to download, take this one)

Legacy binary version (no GUI, but works under Windows Vista)

C# sources

ColorMatrix Viewer. Another program to easily view and edit color matrices…

    After some frustration with nvidia drivers which no longer allow gamma ramp functions using nvcpl.dll in Win7 64 bit, and nvidia’s lock out or other utilities like Powerstrip from directly writing to the color space for inversion, I was glad to see this program.

    Question though – I am working in a 5-monitor setup where I need one monitor inverted. Any possibility of a toggle or command line mode with monitor number so that I can invert only the one monitor?


    • #2 written by Yaurthek
      about 5 years ago

      This is currently not possible to choose only one monitor, but it would be relatively easy to implement.

      Well, actually I just did it after reading your message. ^^

      Try this version : (x64 only)

      I added a system tray icon with a menu on the right click, allowing to toggle a monitor…
      This is a quick and dirty patch, tell me if something does not work properly.

    Hey Yaurthek,

    Firstly thank you for the app, it’s exactly what I was looking for and works perfectly. I don’t know how hard it would be to implement something like this, but if you ever find yourself updating it in the future, and if there are others who’d be interested, it’d be great to have a negative green option like the F9 negative red.

    Either way though, thanks again! This is so useful to me – it’d gotten to the stage where I just couldn’t get any work done after a certain time of night. Now I need never sleep again! 😉

    • #7 written by Yaurthek
      about 5 years ago

      Thank you for your kind words 🙂

      Regarding your request, you will be happy to know this is actually something I’m planning to add in the next version.

      I don’t know when though… Sorry.

      Meanwhile, beware of sleep deprivation!

      • #8 written by phntm

        In the next version, I think grayscaling the red/green filters would be a good thing to have. I’ve shared your application with my friends and coworkers and they like the grayscaled filters more the non-grayscaled. I just edited the code (64 bit only) and used that lately (I think I mentioned this before. Sorry, if I did repeat myself).

        I liked how your beta has the smooth/blending transitions. Someone asked me if there was a way for the user to designate a certain area/window/screen to have a different effect (like two modes active simultaneously or one mode active with an area that is not affected). I’ve tried to dabble around with the code, but to no avail.

        I don’t know if this would be a good thing to have, but I don’t think that it’s really necessary: for some background, they wanted to have NegativeScreen affect everything except for a window in Photoshop or for streaming videos on Youtube. Still eager for next big release. If you think I can help with anything, just let me know (^_^).

        • #9 written by Yaurthek
          about 5 years ago

          In fact, I would like to allow the users to choose theirselves the color transformations and the key bindings, using a config file.

          Of course, I will add some default parameters, as I think not everyone want to write theirs own color matrices… 🙂

          Also, it is theoretically possible to filter a window out, but it would mean going back to using some hack instead of the new fullscreen mode. It would also mean adding some way to designate a window to filter, in a way or another, and it is not something I’m willing to do…

          If you are interested though, throw an eye at this:

          • #10 written by phntm
            about 5 years ago

            Ya, I personally think toggling to normal mode is fine. I’ll probably just make a customized version for him when I get the chance to play around with the MW_FILTERMODE_EXCLUDE. Oh, I forgot to ask about NegativeScreen’s support for multiple monitors. A coworker was experiencing some flickering on his secondary monitor when scrolling on either monitor and when moving the cursor between screens. Both monitors are Dell 1900×1080 on a Dell Pricision T3400 with Intel Xeon, running 64-bit Win 7, using 32-bit color. Any ideas?

          • #11 written by Yaurthek
            about 5 years ago

            I keep hearing about flickering, but I can’t see what could possibly cause them :/
            The use of the full screen apis, as in the beta, should fix that though…

            Oh, and good luck with the window filtering, I would be interested to see the result!

          • #12 written by phntm
            about 5 years ago

            There’s another coworker with the same specs and he doesn’t experience the flickering so I’m at a loss. If it’s not too much trouble, could you send me the source code for the beta?

          • #13 written by Yaurthek
            about 5 years ago

            The bitbucket repository is up to date. The last clean changest is here :

            The last changesets depend on the SlimDX library (I’m trying to auto toggle inversion, based on current screen brightness. It works almost fine, but it’s not perfect…)

  • #14 written by DS

    As a person with low vision problems, your app has been a lifesaver. Using black background and white text makes the page much more readable to my eyes. Thank you.

    My only problem is with Google Chrome in win 7. With negativescreen running, when I click on a hyperlink, it takes long enough that Chrome moves my tab to a new window. Lately, I have started doing Win+Alt+N before and after clicking on a hyperlink as a workaround. But I am wondering if there is another way to solve this.

    • #15 written by Yaurthek
      about 5 years ago

      Thanks for your comment, and for using NegativeScreen.

      Unfortunately, I don’t have any idea what could cause the behavior you are describing, so I’m afraid I can’t do much…
      Did you try the beta version I posted a while ago in the comments? (NegativeScreen2beta warning: works only on Seven x64)
      It may help.

    Great App!! any way to get it working with windows magnifier? every time you invert, the docked magnifier box goes away.

      Hmm, this should work fine in the next version. I posted a beta executable in a comment below, if you want to test…

    Wow! Awesome app! Thank a lot for it. After I started using negative in Linux’s compiz-fusion I long such function in Windows. Fortunately Win 7 provided Magnifier with it but at first a had a problem with Alt+Ctrl+L (I’m PL key: “ł”) and then I realized I’m so used to “Win Classic Theme”, that I can’t endure reflections etc. in Aero. Finally I came back to “Windows Classic”. You’ve given me a new hope :-).
    Maybe you or somebody of this page reader’ have some idea or theme for Aero so as it be more readable?

    Once again, thanks for making easily the best inversion utility out there
    I had an odd flickering problem earlier with the original on a gtx580 graphics card and the beta version you released in the thread fixed it, if you want any details I’ll let you know, so far i like the smooth transitions in the new version.

    I also had a chance to play with the windows 8 inversion feature, its very cool, it wireframes all the UI elements and inverts most colors, but most significantly, it seems to detect most (not all) images and does not invert them, if it only had your smart inversion filters it would be perfect.

    • #21 written by Yaurthek
      about 5 years ago

      Sorry about the long time coming answer, I did’t had the time to check the windows 8 rtm before yesterday…
      what do you mean, “the windows 8 inversion feature”?? I didn’t see anything like that. Are you talking about the high contrast theme?

      apart from that, I’m glad the beta version worked better 🙂

    Thank you, sir, for this awesome program. My mother set a couch on top of my laptop (true story), causing the screen to crack in one part, and negate every color on display. This switched it back so it only looks half bad. Thanks for the time you put into this!

    You should change the order of the comments on this website, so new comments appear first, and older ones later. The new comment are better then the older comments = more downloads.

    The program works very well on my Tablet PC. Thanks a lot. I only wish I could have found this program earlier.
    The Microsoft Magnifier’s color inversion really buggy in windows 7. When I used the Microsoft magnifier with color inversion on and change screen orientation from landscape to portrait half of the screen would become the corrupted. I tested it on other computer, laptops and tablets, all of them had the problem. I even emailed Microsoft and told them where the error was occurring and how to fix it, but the didn’t really care.

    Thanks to your program NegativeScreen, I can read books on my tablet pc in portrait mode with color inversion. My eyes thank you.

  • #36 written by Puck7845
    about 5 years ago

    So that flickering bug sounds a lot like what I’m getting right now, I’m running win7 x64 sp1, with two nVidia GTX580’s, and two monitors, one 1920×1200 and the other 1280×1024. Decreasing the frame rate will cause longer black screens (and vice versa), but seems to have no effect on the frequency of the flickers. I tried running in compatibility mode for vista and 7 (no sp), but to no avail.

    • #37 written by Yaurthek
      about 5 years ago

      What kind of bug do you have exactly ? there is no known flickering bug on 7 and hopefully no more on Vista either…

      • #38 written by Innate Distress
        about 5 years ago

        I also have fairly severe flickering issues with Windows 7 SP1 64-bit, with two Nvidia GTX 670 cards (driving three monitors at 1920×1200). I would really like to use NegativeScreen since I think it’s awesome (especially for people with eye floaters), but the flickering has forced me to go back to using Windows Magnifier (which doesn’t exhibit any flickering).

  • #40 written by phntm
    about 5 years ago

    First off, I would like to thank you so much for this application. I’ve been using Redscreen on my Mac for a while and was looking for a Windows equivalent to no avail (until I found NegativeScreen that is). I was wondering if you can make something similar because manually reducing the green and blue of the monitors works to achieve the red effect, but it would be nice to be able to make that adjustment from the application instead of from the monitors (that way, control of the red wouldn’t require going to the monitor color settings and toggling would be easier).

    I know that this would require additional time for developing and testing. If you don’t have the time to do this, can you teach me how? I’ve looked at your source files, but I’ve had very little c# experience and am clueless. Thanks.

    The link for Redscreen is:

    • #41 written by Yaurthek
      about 5 years ago

      Are you only looking for a red filter?
      If so, it would be very easy for me to release a new version and add this feature.

      If you would also like to be able to change the brightness, it will have to wait a while for the next big release I plan to do 🙂

      • #42 written by phntm
        about 5 years ago

        Wow, you reply quick! From what I know, red and green are the usual choices for night vision (I personally prefer red, though). I’m not in any rush so, if you’re going to add this feature, just include it in your next big release. Would the filter be independent of the inversion mode?

        • #43 written by Yaurthek
          about 5 years ago

          Yes it would be independant. I could add it right now on a Win+Alt+Fn key.

          • #44 written by phntm
            about 5 years ago

            So that the inversion mode can be changed while the filter is active? That’d be so cool. Thanks! At first, I didn’t think that you would consider it unless a lot of people supported the idea. I’m still very impressed with the pure keyboard idea through Win+Alt+. Well, if it’s not too much trouble (or you have nothing else to do), then sure. When do you plan your next big release to be?

          • #45 written by Yaurthek
            about 5 years ago

            By independant I was actually meaning that it would be another mode.
            But I can do a red negative mode too ^^ (and it’s actually better, according to my tests).

            I’m not always keen to add some new stuff people ask me to, but in this case I think this feature would fit perfectly in NegativeScreen.

            And finally, I (unfortunately) do have things to do, that’s why I don’t plan any release date… 🙂

            As it is a rather simple update though, I made a 1.11 version with red and negative red filters bound on F9-F10. I Hope it’ll help you to wait for the next big release.

          • #46 written by phntm
            about 5 years ago

            Oh, just out of curiousity, how come you gave up on gray scale and sepia? This works perfectly! Thank you so much! Ya, F9 would be best for night vision. For the most part, it’s like what I use. The only difference is that it’s not gray scaled, which is just my personal preference because it gets hard to distinguish between colors that are close sometimes (such as a yellow folder on white background) due to the monochrome, but, again, that’s just a personal preference and isn’t worth making a new version for in my opinion. I’m very satisfied with v1.11 as it is now, but I’ll still be eagerly waiting for the next big release (I’m very anxious about what is to come). Thanks again! Let me know if you ever need anything! (I’ll do my best to help if i can).

          • #47 written by Yaurthek
            about 5 years ago

            Well, gray scale and sepia were not very useful for the purpose of NegativeScreen, just funny at most. I will provide a way to use them anyway in my future version, and much more!
            What do you mean, gray scaled? Are you still speaking of the red filter?

            edit: don’t mind my last question, I see what you meant, and this is again a very nice idea 🙂

          • #48 written by phntm
            about 5 years ago

            I see. I didn’t use them much, but it was something I noticed was different from the README. I went to the source code and just changed Negative to NegativeGrayScale. I wanted to take it a step further and make a 32-bit version, but I don’t know how so I didn’t consider it as a potential update (in addition to the change being so minor). I’ll be sure to test out your beta when I get to work tomorrow.

    Love this app; great idea and great work. I came across this because newer versions of the nVidea Control Panel seem to strip this functionality (color graph). I support 5-monitor workstations for Radiologists who work 8-10 hour shifts in dark rooms. Their 5th monitor runs an application that is too bright and unconfigurable. I’m not sure we will prioritize looking at your code for this or not yet. But, have you considered a feature to set which monitor(s) get inverted or not? Do you think it’s possible?

    If I’ve caught your attention… Let me throw a little more complexity in to the mix. These stations run Win7-64 and we disable Aero (because one of the applications auto-disables at runtime if not). 3 of the monitors are 1280×1024 (Landscape) and two are hi-res 1536×2048 (Portrait). We ONLY want 1 of the Landscape monitors to be inverted.


    • #50 written by Yaurthek
      about 5 years ago


      With the current version, it would actually be quite easy to do what you want, as each monitor has an independant overlay.
      The only thing to add would be a screen selection interface, to allow the user to choose the inverted monitors.

      Regarding aero, the current version doesn’t need it. It’s just very slow and cpu intensive without…

    Works AWESOME! for what i do, which is staring at charts for 8 hours a day, having a BLACK background on everything is exactly what my eyes and brain need to keep from hours of pain. it’s nice that it inverts EVERYTHING that Win/Java wanted to keep white (wouldn’t let me change using other means). on Win7-64, it works perfectly, and F1/F2/F4/F6 are the easiest views on my eyes. i think F2 is the best overall. F1 is also nice and has that CGA/EGA look to it at times! nostalgic.

    the ONLY issue i have (and maybe it’s just normal) is that it takes a while for NS to kick in after bootup. it’s in the start-up folder, but seems like it doesn’t kick in for around 30sec (or Win7 is busy with other garbage before it gets around to loading up NS). if you’ve got ideas on how to get Win7 to load NS sooner, i’d be keen to hear it. otherwise, it’s a minor “inconvenience” since i tend to keep my machine on 24/7 until it NEEDS a ‘boot.

      Wow, thanks ^^
      NegativeScreen is written in C# .Net, and is therefore dependant on the .Net Framework.
      The .Net Framework is a rather big thing which can take a while to start up, and unfortunately I can’t do much about that.
      30 seconds seems very long though, maybe you have a lot of things starting at the same time, or your pc is very slow…

    I’m looking for an option to make my screen darker, is it possible to make something like this?

    • #56 written by Yaurthek
      about 5 years ago

      It surely is possible to make your screen darker, but then NegativeScreen is not the thing you need.

      Instead, it is better to physically change the brightness of the screen with you monitor buttons (on a desktop monitor) or with Fn key combinations on a laptop (or in Windows settings).

      NegativeScreen only inverts the colors of your screen, as the name suggests…

    I love negativescreen, makes working at night a pleasure, now everything can be skinned black rather than just the few programs that support it

    Question: one of my older machines is still on windows XP, but it has an nvidia card so i can adjust the color graph, what do your smart inversion graphs/values look like? i’m trying to replicate it using the nvidia color graph

    • #58 written by Yaurthek
      about 5 years ago

      I use some color matrices to transform the colors, I doubt you can use that with your graphic card settings, but here is the matrix anyway:
      { 0.3333333f, -0.6666667f, -0.6666667f, 0.0f, 0.0f },
      { -0.6666667f, 0.3333333f, -0.6666667f, 0.0f, 0.0f },
      { -0.6666667f, -0.6666667f, 0.3333333f, 0.0f, 0.0f },
      { 0.0f, 0.0f, 0.0f, 1.0f, 0.0f },
      { 1.0f, 1.0f, 1.0f, 0.0f, 1.0f }
      (don’t mind the ‘f’s …)

      It combines the inversion of the colors, with a 180° hue shift in HSL color space to get the “good” color.

      I hope this help, and thanks for using NegativeScreen 🙂

      Don’t you have something similar to this?
      with a “View problem details” button?

      If the window does not look similar, could you make a screenshot or write down the exact text?

      If you just don’t have the detail button, you can try to find more informations in the event viewer.
      Type “Event Viewer” in the start menu to access it, then go in the Windows Logs/Application section. You should see a line about NegativeScreen, and the crash details.

      You can copy paste the infos, of make a screenshot if you prefer.

    about 5 years ago

    GREAT application!

    I’d edit it myself, but I thought it would be good to send to you. This works like a charm on dual monitors, but my secondary monitor is rotated 90degrees (portrait mode). The inversion will not fill the bottom 2/3 of the screen UNLESS I drag some application’s Title Bar to the VERY bottom of the screen. I think there might be some max resolution you didn’t take into account when doing Heights. Feel free to email me with questions if you don’t see what I’m talking about!

    Thanks again!

    • #69 written by Yaurthek
      about 5 years ago

      Thanks for your kind words!

      Unfortunately, I think I see what you are talking about, the random bug when using different resolutions on several monitors.
      If i recall, the bottom of your screen stays black, is that it?
      Does it work if you switch your main screen, or, if you move your vertical screen to another virtual location?

      I encountered the problem before, but I didn’t manage to find the solution.
      Theoretically, the entire screen size (every monitor combined) should be correctly detected.
      I suspect another bug in the api, but I’m not absolutely certain this is not me…

      You say it works if you move a window to the bottom of the screen, though?
      That’s unexpected.

      I will send you an email…

    I was searching for something like this since the last /inf years. Awesome. Sweet. Thanks.

    I didn’t test it yet, but I hope it will be okay. I don’t know how smart modes work (several comparison screenshots with a photo, some text and a palette would be great), but some time ago I found out that standard color inversion and then 180 degree hue shift works nicely (which is equivalent to basically inverting only luminosity and leaving hue and saturation intact) – it makes it easier to spot details on darker photos without making them look completely outlandish (but just a bit). I hope there’s a mode like this (your descriptions don’t say). F2 (smart 1), perhaps?

    • #71 written by Yaurthek
      about 5 years ago

      Well, you should have tested it :p
      The so called smart mode is in theory exactly what you described, but unfortunately the way it works internally (I can’t do anything about it) makes it so the final colors can’t be exact.
      I can only approximate what I want, that’s why there is so many modes: some give exact pure colors at the expense of less saturated colors, while some other give bad pure colors but a better overall.
      I did some screenshots a while ago I never added and you are right, I will put them here. Thanks for giving be the motivation ^^

      • #72 written by RomanX
        about 5 years ago

        Okay, tested on a non-linux machine. F2 (smart 1) is awesome.

        Performance without Aero is, as expected, not so awesome. Will use only on the machines with Aero on. I wonder why is that so, as F.lux is fast and changes colors too (just doesn’t invert them). I’ll use F.lux on the machines that are too slow.

        By the way, without Aero task bar flickers when clicked. I guess it’s jumping in front of the overlay and without Aero the update takes longer than 10 ms. I wonder if it could be reduced if you’d update on mouse button down?

        • #73 written by Yaurthek
          about 5 years ago

          I’m glad you find it useful 🙂

          The way NegativeScreen and F.lux work are very different.
          As much as I understand, F.lux uses a custom color profile to do its job, while NegativeScreen is what could be called a dirty hack.

          My program actually uses the Windows magnification API, at a 1:1 magnification factor, and takes advantage of the provided color transform methods.
          I found nothing better to do the job.

          So you are right about the flickering, the magnification window on top of the screen must be refreshed quickly as possible for the animations to stay fluid. The taskbar want to be topmost but the overlay want too…

          I don’t handle any mouse event though, the window just let them pass through it. I can’t do much about this. I hope the new fullscreen functions of the API in Windows 8 will improve the situation. (with aero only, probably)

    I have been using this awesome utility since I came across it on StackOverflow last year, and am truly thankful for it. I use Ubuntu at work and have the screen inversion set to Super + Z to make it possible to hit one-handed. I came back here because I kept getting sick of hitting the wrong key at home so I could download the source and change it to Windows + Z, but the links to the sources and original binary don’t seem to be working anymore. The horror!

    I see you’ve been making updates and figured maybe a) it’s temporary, b) it’s just me, or c) you didn’t know the links were broken. Can you make these available again, please?

    Thanks again!

    Just to clarify my first post….I have four monitors, and when I disconnect the one, the program runs fine, but as soon as I try to connect the 4th again and run the software, the computer reboots. It seems to only handle 3 monitors, which agreed, is more then the average user uses, but I was wondeirng if there was simple way to get this working?
    I also tried to run the software with 3 monitors and then connect the 4th while its running but the results were the same. I finally started seeing light at the end of the tunnel with this awesome simple piece of software and I’d love to have my four monitors going if its not too much trouble.

      The zip comes with two versions:
      – NegativeScreenX86.exe, which is 32 bits compiled,
      – NegativeScreen.exe, which is 64 bits compiled.

      If you have a 32 bits system, you can’t start the 64 bits version, but if you have a 64 bits one, you can start both versions.
      The problem is that the Windows API I use is buggy, and the X86 version won’t work as expected on a 64 bits system, hence the warning…
