OPEN LOOK uses a specific set of colours for its 3D effect:

	white: used for highlights on the NW side

	BG1: Openwindows.WindowColor in XView/Sun olwm

	BG2: reduce brightness of BG1 by 10-15% (used for recessed buttons)

	BG3: reduce brightness of BG1 by 50% (shadow on SE side)

	black: default text, window outlines etc.

In Sun's implementation of OPEN LOOK BG1, BG2 and BG3 are always contiguous
entries in the colormap with BG1 at the lowest index.  This is probably
true of any implementation of OPEN LOOK that uses olgx to provide 3D
objects.

In principle different groups of windows may have different BG1s but Sun's
version of olwm does not support this at present.
