One of Windows 8’s new features will be the ability of Aero Glass to automatically adapt to the colour of your desktop background, but if you can’t wait for its release then you can get similar functionality now.
Aura is a little tool whose sole job is to calculate the average colour of your desktop background or – if you prefer – an active window, and automatically set the Aero Glass colour accordingly.
There’s no installation involved: download, unzip and double-click the program to put its icon in the Taskbar’s Notification area.
To see it in action, right-click the desktop and choose Personalize, then pick a background with a markedly different colour. As soon as it’s changed, you should see the Aero Glass colour change too.
