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 of little value with today's hardware. You can run this example with the "--rgb" flag to see it use an RGB visual. We should probably get rid of this example.
