I have red-green color blindness. I know my vision isn't monochromatic. You are aware that there are six types of non-monochromatic color-blindness conditions, right? So what you can see is not a conclusive test of what other color-blind users can see. As for how common it is, here's Wikipedia: http://en.wikipedia.org/wiki/Color_blindness#Prevalence Red-green is listed as 7 to 10%. OK, so I picked the high end. But I certainly wouldn't say 7% is "nowhere near" (your words) 10%. It's still a lot of people. It's very simple: do not use color as the only means of conveying information. It's even in the HIG: http://library.gnome.org/devel/hig-book/stable/design-color.html.en#hsv -- Shaun McCance http://syllogist.net/ _______________________________________________ gnome-list mailing list gnome-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gnome-list
