A better idea maybe would be to improve the random colors script,
so that it would allow to select color ranges or gradients.

Here are two examples:

The blobby cube was colorized with Wings3D and Jotero's Kitten
was colorized in Shade 3D with a color gradient script. Both techniques
uses faces (or in case of MoI patches, or imported .obj faces into MoI)
like the random color script for MoI.
