I once worked on a commodities-trading package, and we had coded "buy" opportunities to
appear in red and "sell" opportunities to appear in green in a grid.  Three months into
the project the project sponsor asked if we couldn't add some kind of status indicator
other than the amount... that's how we discovered he was color-blind (it also explained
why he kept asking for the "hot dog" color scheme).  We compromised by keeping the
red/green colors, but adding bold or italic attributes for buy and sell (normal
attributes for hold).

I was never happy with the bold and italic solution, but by that time we were on a very
tight deadline, and it could be done in five minutes.  I'd have been a lot happier if I
could have included a small icon next to the message.
