Testing if colors equal

Use Color.X.equals(c) for your if cases that are like c == Color.X. You're testing if the objects are the same instance, instead of if they're considered to be equal to each other.

You could also use c.equals(Color.X) like you did for Color.RED, however many people prefer the other way to safeguard against a NullPointerException for cases where c is null.
