Kincade saddles are cr@p. You get what you pay for. You can try to have the whole saddle dyed at a saddle shop, but there's no guarantees that will work, or if it does, the dye could rub of on your clothes when you ride in it.
You can buy Kincades new for right at $305, so a used one with bad color rubbing I would price at $100 or $125. You'll be lucky to get that for it.
