Question of the Week / QotW - 10.10.24 - Why wouldn't a person see coloured pen on a whiteboard?

I am colour blind and I have that problem, when I am close to the white board (< 1 meter) I see all colours, the problem comes in when I move away from it. I do not see yellow at all, I see it as green so that is a problem, with lights. Green disappears after 2-3 meters. All dark colours become black after about 3.5-4 meters, so colour charting does not work. Too light a colout disappears at about 3.5-4 meters.
And this is not only on whiteboards, it also happens with overheads and projectors. If you switch the lights off, it is better, I can see the colours from further away but still not green/yellow. It makes interesting reading when you go to seminars and can not see the entire presentation.
