AeroRainbow is the software that can change the color of Aero windows depending on your desktop background's color, or by a predefined list of colors. It can also randomize the colors. Initially, it was designed for Windows 7 to add a more personalized touch to your desktop. Since version 2.7 you can use AeroRainbow in Windows 8. Starting with version 4.0, AeroRainbow supports Windows 10.

AeroRainbow 4.1 is available. Please upgrade your app.Change log:

    • Improved color intensity again. Now looks much better in Windows 7 and Windows 8.x.

  • v2.5: the ability to use your wallpaper or an active window's color as the color for Aero.
  • v2.0: the tray icon option was added as well as colors list additionally to random colors. Notification window is also available.

When the tray icon is disabled, then AeroRainbow will be invisible, e.g. no UI will be shown when it running. In that case, the user can manage the app using its command line arguments.

If tray icon is visible, it has a handy context menu.

Left click on the tray icon to show the current and next colors.

The "Next" color is clickable and will be changed according to rules of the color change (see description below).

There are several options available in the configuration window.

These options are as follows:

  • Rules for colors.
    Always random color tells AeroRainbow to generate and use a random color for Aero Glass.

    Use the colors list option allows you to add your favorite colors to the list. AeroRainbow will use them for Aero Glass.

    Speed - adjusts the speed of color change in "Always random color" and "Use the colors list" modes. Left value means the fastest mode.

    Use wallpaper as color source mode tells AeroRainbow to use wallpaper as the color source for Aero Glass. Windows will be colored close to the color of the wallpaper.

    Use active window as color source - windows will be colored close to the color of the current active window.

    Use only icon color checkbox - use the active window's icon as the color source for Aero instead of the window itself.

    Color calculation mode - define which color of the wallpaper, active window or active window icon has to be used as the Aero color. It can be the Dominant color in the color source or the average color.

  • Use tray icon - self explained.

  • Check for updates - self explained.

AeroRainbow is a portable application and doesn't require installation.

Something you need to know about AeroRainbow

You have to place AeroRainbow to a writable location. It will create and use AeroRainbow.ini file to store your preferences.
No registry or other files will be used. Since version 2.7 I have removed the installer.

Since version 2.7 there are two executable files. The first one acts as a Windows 7's "native" application (no additions required, e.g. .NET Framework).
The second one works as a "native" software in Windows 10 and Windows 8.x, for same reason. They have same codebase, just compiled with different versions of .NET.

Command line and tricks
There are two command line switches available:
aerorainbow /close - closes the currently running instance of Aerorainbow. Useful when you have disabled the tray icon in preferences.
aerorainbow /config - opens the settings window. Also useful without the tray icon.

Additionally, you can force Aerorainbow to use the Russian language for its UI.
Add the following lines to your AeroRainbow.ini file:

If your prefer to use English, then add

AeroRainbow and Windows 8/Windows 10
Although modern Windows versions like Windows 10 and Windows 8 have the built-in feature to colorize the window frame automatically, with AeroRainbow you can get even more! You can control how colors are changing in an advanced way and use the color of the active window as your Aero color source, use its main/average color or define your own color list.

    am i wrong to assume that on windows 10 this aerorainbow can make windows default wallpaper color algorithm to select more intense colors even after aerorainbow is closed? - am i delusional?

    Windows 10 sure would be nice to have...the program runs but it only changes the very outside line border of Windows, not the actual titlebar colors.

    What is the "Dominant Color" option looking for? It feels like it's looking for the one color that is the greatest outlier compared to the other colors on the hue spectrum because when this wallpaper comes up, it turns my aero green, not red. I know where the green is coming from, but what is the math and why?

    It will not work as expected in Windows 10.
    Windows 10 has changed the title bar color APIs.

    Ah, that is a shame. This was one of my favorite apps to run on my Win7 and 8. Any idea if you'll be able to get it working with Win10 or not possible anymore?

    Any chance to add a 'secondary color' calculation mode (so if one color is dominant and there's another secondary color that stands out, use this one, not the dominant or the avg)? eg.: the dominant color on the pic on top of this page is blue and the secondary is white, so white would be used.

    Any way this can also change the (solid) color of the desktop background as well? I donít want a wallpaper, but a single color is boring. It would be nice to have the desktop background change with the rest of Windows now and then.

    Is anyone reading these comments? I'd like an option to use other color than avg or dominant, so if I have a yellow wallpaper with a blue section, the dominant would be yellow and average some tone of green, but what If I'd like to use the blue section for the aerocolor - is that possible to add?

    Sure, I am always here.
    I will think what I can do.
    BTW, it is a good idea to use the lesser used color

    I am sadly convinced that this project is dead. One of my favorite apps to use on Windows 10 ever and the creator refuses to update it. Windows 10 has been out for almost 2 years and we have no support.

    Just in time man. This is working great. Got it running and set to run on startup. One more thing to improve the UI of Windows 10 along with Fluent.

    One thing I noticed is that it does not change the color of the Taskbar/Start Menu/Action Center. Is it possible to do that? It just looks a bit inconsistent if you're actually using a color on those 3 items other than black.

    Nice catch. I will fix the issue.

    I use AeroRainbow in combination with an app named zVirtualDesktop which allows me to have different wallpapers for each desktop in Windows 10. But regretfully, AeroRainbow does not seem able to adjust accordingly. Is there a way to make AeroRainbow perform regular detection of wallpaper change, i.e. every 0.2 second ?

    Flickering is present here too, also when running the program result in a CPU leak completely making my PC unusable.

    Yes, AeroRainbow update to latest version and some flickering when changing color makes the explorer.exe kinda reset/stutter/lag so it's next to impossible to select/open any file in my documents for exemple.
    Any idea sergey ?
