Bored of having the same keyboard in every application?
With AdaptiveKeyboard every application gets its own individual keyboard color!
AdaptiveKeyboard calculates the dominant color from the application icon and uses it as the keyboard's color.
Additional information & screenshots:
The tweak does not have any options to configure.
If an application icon could not be loaded, the color defaults to gray,
that also applies to Spotlight.
The algorithm might change in future versions.
