What version of Solid Edge are you running? To those of you more knowledgable, wasn't this a known bug in one of the versions/MP's?
Maintenance Packs aren't available for "Student Edition".....you might try looking at part painter, and see if applying "[None]" to the "Body" and see if that helps kick the colour mapping back into line.
