Yep I remember someone mentioned a color calibration tool.
On Nexus 1 we had an exellent app but only worked for N1, on SGS2 you can choose between 3 color tint...Any TV LCD has a tint control so why not on Android

Edit: I have found the app
I am gonna test it right now https://play.google.com/store/apps/d...JzY3JlZW4iXQ..
