Phoebe,
I'm red green blind myself, and it is not as straight forward as it
sounds. The problem is that we "see" red and green despite lacking one
of the color receptors (I actually prepared a figure using red and green
once and got a referee comment that red/green blind people would have
difficulties with - which I could attest to being wrong...). We can
distinguish between bright green and bright red! But in between, things
are sketchy. Our brains learned to associate certain gray levels with
either green or red (e.g. on our old BW TV, I did see all the grass as
green, I was flabbergasted at the age of 6 to learn that our neighbor
did not see the colors in our BW TV; Also, I called one of my class
mates in junior high on his ugly green jeans, only to learn they were
washed out black).
My advice: Convert the image to gray scales. If you can't tell the
difference, people with color seeing problems can't tell them apart.
Actually, chose your color scheme so it gives good contrast in a gray
scale image. This also should take care of the much rarer blue
deficiency; and it might cut down on reproduction cost - as everything
should be reproducible on a BW copy machine.
HTH,
Jens
