I'd greatly appreciate a nudge in the = right=20 direction.

I have an array that defines all the coordinates of the mesh and an array that defines the relationship between elements. I have examined using quad mesh, as the elements from the finite element code are quads. The problem I can't seem to decipher is; a typical finite element code will display a unique color for every element. Often two or more colors will be drawn in a single element. Is there a way to create a quad mesh or anything similar that will allow the color to be set on a element by element basis?
