Color bling?

I make some Jewlery and i would like to have bling that would match the color i have. like if im making a red jewled necklace to bling red, how would i do this, i know there should be some way to edit the script but i have no idea what to edit in the script and stuff, so if anyone has a nice bling script and can tell me what to change in it it would be really helpfull ^.^
