There are various forms of color blindness, so there is no one right answer.
For complete color blindness, which is actually quite rare, only the
brightness matters, not the color.  The best approach to easily distinguis
the states is to use separte LEDs.  That way the information is encoded in
position, the LEDs are easier to drive, and you have a much wider range to
choose from.
