It seems like quite an oversight that +Android does not support having a colour profile for the display.  Of the 7" tablets I currently have floating around (Cruz, Nook Tablet, Nexus 7, Kindle Fire HD & XO Learning prototype) I'm seeing an enormous variety of colour representation and I'd really like it if I could make them all look the same.

Especially that last one, where I can imagine a world that would let me apply a base profile to all of them as they left the factory. Sigh.
