OK, so the last time I checked, there were 15 different ubuntu based themes on gnome-look. More than two thirds of those are are the pixmap icons that have been colorized in one shade or another. So what about a community effort to convert the svg icons to (a) different color(s). If anyone is interested, the download link is for a png of the ubuntu color palette. Contrary to popular opinion, it does include several shades of blue, green, and violet, in addition to orange, yellow red and brown. If other people are interested in doing this, sticking to that color palette should save us some work and ensure that any icons that don't need a new paint job will look homogeneous with the altered ones.
