Color is a fun brain speed game. If the colors match then you must tap the screen within a certain amount of time, depending on the difficulty level. However, if they do not, you must do nothing until the time-out finishes. Easy: there are 30 levels and 3 second time-out. Medium: there are 50 levels and 2 second time-out. Hard: there are 70 levels and 1 second time-out. Survival: there's 1 second per level and 5 lives. You lose a life if you get one wrong. You keep going till you run out of lives.
