The standard colormaps are not necessarily existing, and asking for
them does not cause them to be created.  This is confusing to many
people.  One way to cause the standard colormaps to be created is
to run the client xstdcmap.  Another way is to write your own 
routines to create and define the standard colormap properties.
There are interfaces in the R4 Xmu library that you can use, if
you don't have the R4 xstdcmap client on your machine.

The use of XGetStandardColormap is deprecated in favor of the
interface XGetRGBColormaps.
