I am developing a computer based instructional system that uses
the colors green and red for, what would seem to be, the obvious
feedback for correct and incorrect answers. This is coupled with
an audio feedback and the score is kept with a series of green and
red squares. 

It was brought to my attention that since the most common color
blindness is red/green that it would be difficult for some people
to use the visual score.

I would like to find out if there has been any research or if there
is a prefered set of colors to use in this type of situation.


Thanks in advance. 

John Keller
