It may be that your server does not permit you to access anything else.
Run xdpyinfo and check the output for the availability of a PseudoColor
or DirectColor visual.  If all you have is a StaticColor visual, you
can't get arbitrary colors out of it.  (This is true of TrueColor and
StaticGray as well.  These three are the "static" visuals; you can't
change colormaps for these ones.  The other three, GrayScale and the
two I suggested you search for, are "modifiable": you can store into
them.  I'd be glad to mail you the details; drop me a line.)

Well, I just use the files in mit/doc/Xlib.... :-)
