The Color procedure is a constructor for a color data structure.  This data structure is recognized by most ColorTools commands and many plot commands.

The parameter colorspace can be any of the color spaces listed on the ColorTools/ColorSpaces help page.

Color structures can be indexed as lists.  Two structures are considered equal only if their distance (in the CIE76 metric) is less than ${10}^{-\frac{\mathrm{Digits}}{2}}$.
