All right, here's a new script called Extrapolate Colors.

Description This script finds materials used in a set of selected faces, and then randomly applies those same materials to all selected faces that have no material applied.
Usage Run the script from Plugins > Chris Fullmer Tools > Extrapolate Colors.

First select a series of faces, at least one needs to have a meterial applied to it. Then run the script. The script will find all materials in the selection (only materials applied to faces though). And it will randomly apply those materials to all faces in the selection set, leaving faces untouched that are already painted.

Note that the script works on raw geomtery. It does not work on groups or components (but it does work on raw geometry inside a group or component if you are editing a group/component).

PS I've Got quite a few color scripts. I might package them all togther, with some added featires intoa Web dialog based color script and charge a little for it. We'll see though.
