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.
