The Wal-Mart in my town had a handful of returned Christmas Chima sets and my son and I were able to get 70012 Razar's CHI Raider, 70128 Braptor's Wing Striker, 70130 Sparratus's Spider Stalker, and 2 of 70133 Spinlyn's Cavern for only $60 because the boxes were damaged so badly, All but one of the Spinlyn's Caverns were unopened and even then only the Rogon and Eris minifigures where taken out.
At the paint store by where I live they have a wall of cards in a wide spectrum of colors. On the back of the cards is a barcode that their mixer reads and the paint comes out fantastically close if not exactly right. You might want to see if there is any place by where you live that might do the same thing and find sample that you would be happy with for them to make.
