The colors of this diagram are probably wrong. A chromaticity diagram represents colors with a constant Y. I don't know which exact Y would show pure (wavelength) colors but I guess it would be around Y at the half of its maximum. Because at it's maximum we would see only white light and at it's minimum only blackness. So I come to the conclusion that the centre of the image can not be white but should be rather grayish. --BartYgor 11:50, 17 July 2007 (UTC)
- In fact it would be more black than grey (approximately r=g=b=0.33, which looks like this: ). Basically it's impossible to depict this colour space correctly on an RGB monitor, so some form of compromise is inevitable. -- Sakurambo 13:09, 17 July 2007 (UTC)
