For example, <A HREF="http://www.asktog.com/basics/firstPrinciples.html" REL="nofollow">First Principles of Interaction Design</A> by Tog. I've given a two day <A HREF="http://www.dalkescientific.com/writings/NBN/usability.html" REL="nofollow">lecture on usability</A> and there's an old <A HREF="http://www.dalkescientific.com/bosc2002/usability/" REL="nofollow">BOSC 2002 talk on usability</A>.<BR/><BR/>I had a client once who was red+green colorblind, and he wanted a clustering visualization program, so I used a palette where everything was distinguishable. He was very happy. I was there when he presented it at a conference. At the end someone asked about the strange colors.<BR/><BR/>For that matter, GRASP (the old electrostatic surface visualization program) uses red/white/blue because the original author was red-green colorblind.<BR/><BR/>Given the non-trivial number of people who are red-green colorblind, I'm surprised that all the <A HREF="http://images.google.com/images?&q=gene+expression+profile" REL="nofollow">expression display programs</A> use red and green for the display. Yes, the biology is that way, but the software doesn't need to be, so why hinder the 5% of the viewers who have a hard time telling them apart?<BR/><BR/><BR/>There are also international issues related to colors, like in some countries where a certain color is related to death. Or in the US and Europe where "red" implies danger, so highlighting something in red can imply negativity.Andrew Dalkehttps://www.blogger.com/profile/17091314849699854287noreply@blogger.com
