Color ramping

[Bob Basques]

All,

I have the Contour layer displaying fairly quickly now.  The next order
of business is to display it with a color-ramp.

Are there any programtric ways of accomplishing this with the
attributes.  I have elevation attribute on each line that I use for
labelling, I would like to change the colors (color-ramp) via this
attribute.

Aside from assigning every individual elevation (or groups of
elevations)  a color, is there a MAPFILE (or Trick) config that could
make this happen?

Thanks
