R-G colorblindness can refer to either the lack of red cones ore the lack of
green cones (since either will remove the ability to distinguish between red
and green) -- it could be that he has one, and I have the other.

Most the statistics I've read (multiple sources) place colorblindness at
about 8-10% among males, and about 4% in the population overall -- about the
same as the number of Netscape 4 users, if the stats on this list are to be
trusted. (-:

Worried about whether your colors will cause problems for R-G colorblind
users (who may comprise as much as 1/25th of your readership)? There's a
free online tool here:

It can display your website as a color-blind person would see it.

Funny you should bring this up, I actually had a friend of mine who is R-G
color blind and he reports that he is able to view it quite well. However,
your point about statistical backing for designing with such people in mind
is valid. By the way, last I heard, it is something like 3% of the male
population that is effected with this. . . who knows.
