3   *  color.h - header for routines using pixel color values.
4   *
5 – *  Must be included after X11 headers, since they declare a BYTE type.
6 – *
5   *  Two color representations are used, one for calculation and
6   *  another for storage.  Calculation is done with three floats
7   *  for speed.  Stored color values use 4 bytes which contain
