Unfortunately, negotiating colormaps between clients has only recently
been standardized and many older programs go not yet use the standard
methods.  Look in the Inter-Client Communications Conventions Manual
(ICCCM) for details.  Both your clients and window managers must follow
the ICCCM for good results.  Most clients and window managers follow
the (now out of date) X11R2 draft ICCCM.  If your window manager uses
these, you should write your client to use them, too, until your window
manager is updated.
