I don't think it will help with color, but it is a decent enough tool if you don't know where to start.
As for the 50-60 FPS request - just about any mid range card can do that if you play around with game settings. If you think setting max settings is what you want, even a 980 Ti can't do that for all games at 1080P (I know, I play at 1080P with a 980 Ti).
