Looks right to me. The only other thing I do is to destroy the
Colormap that XForms has created with XFreeColormap() to keep the
Server from getting polluted.

How do you know you're getting the "wrong" Colormap? Are you querying
the XID of the Colormap in your drawing handler? What does xwininfo
say?

Finally, for such a relatively small number of colors, why not use the
Colormap XForms hands you and just add what you need rather than
creating your own Colormap and having to deal with all the color
flashing?
