If you take your TT to a dealer, explain your situation. They often will have a kit of the crayons in different colors to match. Believe it or not, new units, especially some of the cheaper ones, need some touching up. They usually go through the new units and used ones only a couple years old. They might let you borrow the crayons or charge you a nominal fee, but if you can find a crayon at a store that matches well, that would be best.
