It is important to NOTE that two red/green color blind students did
NOT see red or green.  The experience always occurred under florescent
lighting which is flashing at 60 hertz.  It is likely that the
flash rate has to be under 60 hertz to get red or green.  
Yellow has not been reported by the blue/yellow color blind.
So it is likely to require a flash rate under 60 hertz as a
carrier or refernce frequency.
