[MAPSERVER-USERS] color theming shapfiles

Check the docs.
For the layer, check out the CLASSITEM.
For the classes, check out EXPRESSION.
And if you need more help, just ask.

Here's a super-simple example to get you started:

LAYER
  CLASSITEM "population"
  CLASS
    NAME "big city"
    EXPRESSION ([population] > 1000000)
  END
  CLASS
    NAME "small town"
    EXPRESSION ([population] < 10000)
  END
END
