A large number of people are red-green colorblind; I've seen anything from 8% to 12% of Caucasian males. Anecdotally, my father is colorblind, the guy across the hall is, and so is my next-door neighbor. (For females it's only about 0.5% of the population due to the X-linked nature of red-green colorblindness.) Almost all "real world" interfaces, such as traffic signals and signs, retail packaging, etc, is designed with this in mind. There are plenty of other colors to choose from! Good page on red-green colorblindness in computer interface design here: http://www.designmatrix.com/pl/cyberpl/cftcb.html (Note that red-green colorblind people often see red and green as "brown," so there shouldn't be any distinctions between brown and red or green either). --Jeremy _______________________________________________ TriLUG mailing list http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ: http://www.trilug.org/~lovelace/faq/TriLUG-faq.html
