Political maps use 2-level coloring schemes.
In what context? AFAIK, generally people use 4 colours, typically pastel colours for political maps.
Main color is selected as to avoid 2 neighbour countries having the same color. It's shade is selected randomly.
Again, in what context? Is your mail a proposal or does it describe the current state? In any case, random colours doesn't sound right.
The problem is to select such N (N about 8) colors generators, and such colors for seas, rivers, city and country labels, and other objects (borders, river/mountains/island/sea labels etc.), that makes maps most readable. [snip] Anyone with better idea for coloring?
How about a predefined colour scheme where the software could select random colours among the predefined set? I'm not sure if "randomly" means "random RGB values" or "a random colour among a predefined set", so we may be talking about the same thing. In any case, even if we are, the predefined colour set should be reconsidered IMO based on what the maps in that link look like.
