IME "prototypical colors" are greitly subjectiv. I've recently thought that maybe a more exact approach would be to use "color density" charted over colorspace... To keep things simple, let's say each word's definition consists of 3 levels - a core of "prototypical C", surrounded by layers of "hue of C" and "C-hued". You'd first have the various-sized blobs of "prototypical" colors scattered 'round the area much in the same way you have exact hues on your current color maps, only with small margins in the color rather than strict single colors - the primaries probably *smaller* than secondaries. (Deciding on a stereotypical black is trivial, but different people probably have vastly different ideas on what's a stereotypical pink.) Some secondary (and all tertiary) "prototypes" would likely end up partially or wholly overlapping with the "hue of" regions of various primaries, eg. English "indigo" can be seen as a hue of "blue" or "purple", and thus "prototypical indigo" would have to overlap with both "hue of blue" and "hue of purple" in this system. To wrap things up, no "hue of" layers could be left as the only descriptions of any colorspace point - they would also have to be in the "C-hued" area of some other (probably nearest primary) color. Obviously if something _isn't_ a pure / stereotypical color, it has to be tinted with something else, no? Again, I suspect this zone would be the largest for primaries but smaller for others. I could rant on about how this system could be used to define exactly whether a color is primary, secondary or tertiary, but I'll put this up for commenting first... Oh yes, and I imagine illustrating this sort of a color map would be damned difficult. You'd probably need either LOTS of 2D color maps, or a few good fully 3D ones... John Vertical
