The Motif Window Manager (mwm) gobbles colors for its own use. 
Remember, that 3-D effect is achieved by using 3 colors (highlight,
background, shadow) for the window frame with the focus and 3 colors
(highlight, background, shadow) for windows without the focus.  Then 2
more for active foreground & inactive foreground, for a total of 8. 

In the 1.0.* releases it gobbles the colormap entries even if it doesn't
use them (e.g. if you use black for active & inactive foreground and
shadow colors).

If you have a 16 cell colormap with an application which needs to display
16 colors simultaneously, you can either use a server with a bigger
colormap (we switched from VGA to a Paradise 8514/A) or have the app
install its own colormap (which will make other apps' colors look wrong).
