Approximate colors can be assigned to areas on the CIE
Chromaticity Diagram. These are rough categories, and not to be
taken as precise statements of color. The boundaries and the
color names are adapted from Brand Fortner, "Number by Color",
Part 5, SciTech Journal 6, p32, May/June 1996. Any attempt to
depict the gamut of human color vision on a computer monitor
must be accompanied by numerous qualifications and exceptions.
In the first place, you cannot display the range of human color
perception on an RGB monitor - the gamut of normal human vision
covers the entire CIE diagram while the gamut of an RGB monitor
can be displayed as a triangular region within the CIE diagram.
Another qualification is that the hue and saturation associated
with a given color name can vary over a considerable range. Add
to that the variations with different kinds of display monitors,
and you rightly conclude that an accurate rendition is
impossible. With all those excuses, however, it still might be
instructive to provide a rou
