[Mapserver-users] Changing Layer Colors on-the-fly

[Steve Lime]

You can use the REQUIRES parameter to toggle between 2 seperate layer
definitions. For example:

LAYER
  NAME 'photos'
  ...
END

LAYER
  NAME 'county_without_photo'
  GROUP 'county'
  REQUIRES '![photos]'
  ...
END

LAYER
  NAME 'county_with_photo'
  GROUP 'county'
  REQUIRES '[photos]'
  ...
END

Depending on the status of the photos layer only one of the county
layers will be used.

I would like to change the colors of a layer
when another layer is turned on. (Specifically
when I turn on air photos I want other layers to
change to a color that can be seen easier.) 

Anyone have suggestions on how to do that?
