As a protanope, and knowing that lots of folks with interest in graphics frequent this newsgroup, I thought I'd call everyone's attention to the article entitled "The End of the Rainbow? Color Schemes for Improved Data Graphics" which appeared in the 5 October 2004 issue of the American Geophysical Union's weekly newsmagazine EOS. A Web site with the sample color schemes and a copy of the article is at http://geography.uoregon.edu/datagraphics/
