I was looking at a review for Cyanogen Mod 6 ROM on the EVO and there is an option for screen rendering that allows users to shut off all but a specific color on the screen (green, red, blue,....). Not only does it look sweet, but it is supposed to save battery life.

Anyone know if this is possible on the TP2?
