Cyc has three separate vocabularies for representing color, addressing the
issues raised by Ferrer i Concho and Sol. At one extreme is the concise
notions of ChristmasColors and HalloweenColors color schemes that utilize
fuzzy sets RedColor/GreenColor and OrangeColor/BlackColor. On the
other extreme is the RGB color vocabulary that defines a color in
terms of its measurements of Red, Green and Blue light.
In a dialog with Cyc, users would prefer to use the fewest words in a
compositional form (e.g. "green as grass", rather than the hypothetical
GreenAsGrassColor).
Cyc uses compositional notation -
(ColorPerceptionCategoryRangeFn YellowColor RedColor) denotes the range
of colors between (and including) yellow and red - because you simply
cannot have a word predefined for all possible concepts.
