This particular example demonstrates the difference between true color
and indexed color visuals.  Apparently your X server / hardware doesn't
support indexed visuals, which isn't surprising as they are obsolete and
increasingly rare.  You can run this example with the "--rgb" flag to
see it use an RGB visual.  Also, I'd suggest "simple.c" as a better
starting point.
