I'm not colourblind, but I have noticed there's a standard arrangement of colours on a set of traffic lights, with the red on the bottom. Also (this is a little harder to see) the different lights have different shapes. Around here, for example, the red light is octagonal, like a stop sign. The best I know is to use a grey scale. But we'd want a grey scale to be what appears on the screen, not a colour gamut that might not match what some colour-blind person sees. My friend's colour blindness is not just that some primaries don't work; it seems to be a complicated interaction between primaries. I don't understand it either. -- hendrik > > HTH _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
