Re: [OpenMap Users] where to find map data files

Chuck,

You could sample colors and key the AreaShapeLayer as Carston and Don
suggest.

Pastel colors: http://www.amaps.com/collecto.html
Michellin colors: http://www.amaps.com/michelinwall.htm
Bright colors: http://www.amaps.com/tyvekwor.htm
Gabelli colors: http://www.amaps.com/gabelli.html

For the 4-color problem, there are algorithms online if you have all
the vertices:

http://mathworld.wolfram.com/Four-ColorTheorem.html

But then again:

http://www.icaci.org/

Some maps of ancient battles make good use of color:
