I'm not a great expert on X, but AFAIK a colormap is where X looks up
the color given its RGB values. The default colormap is a colormap used
for an X application unless it sets up its own colormap.
If my interpretation is correct, you cannot have more distinct colors
than the number of cells in a colormap.
