Using prime numbers to step through a table insures that every position of
the table will be selected, using three different prime numbers gives (in
this case, 256) different combinations.

You might want to use larger prime numbers and add each to a 16 bit value,
using the resulting high order bits as the color value.

Sounds like a fun thing to [lay with.
