It would help if you told us what hardware configuration you have.  For
instance, if you're using an SGI machine with IRIX 3.3 by default,
the X server is started so that there are only 16 read/write colormap
cells for an 8-plane machine.  The rest are "preserved" for GL clients.

For a sample colormap program, try my cpicker application which
dynamically modifies the installed colormap.  It installs a new
colormap for an application window, and manipulates its entries.

Last time I checked, cpicker was available on expo.lcs.mit.edu in the
contrib directory as cpicker.tar.Z.
