Well, I ended up working on this patch as procrastination for my
other responsibilities :P

New sample image with yellow silk, silver plating, and bare copper pads as
options: http://i.imgur.com/ElQYT.png

The copper plating option is still a bit too peachy looking, so I'll try to
fix that up tonight. If anyone has RGB colour suggestions, I'll try them
out. I'll submit the new patch some time this weekend.
