The next new feature of the upcoming Windows 8 operating system has been revealed: Windows Aero Auto-Colorization. What does it mean? It basically means that Aero will change the colorization of Windows automatically based on the underlying color. If you have green background, for instance a green desktop wallpaper, then the window color will also be set to colors in that spectrum.
The same is true for other colors. The change is accessible in the Personalization > Windows Color menu. Take a look at the screenshot below to see how the new menu looks like.
Just click on the automatic color icon in the upper left corner of the color section screen. A click on the Save changes button saves the new setting and the window colors will change from that moment on based on the underlying color.
Look at the following screenshot to see the effect.
