Not going to find paint codes for this game. Best bet is to go to Home Depot or Lowes and get a bunch of those paint strips to take home and match. I've seen this game painted so many different ways. Mine is like the second one down in this link.

As far as the instruction strips. You'll probably have to make your own on yellow paper and cut them out and place behind the plastic piece. If yours is missing I can take a picture of mine so you can see what it's supposed to read.
Good luck... It's a fun game and a LOT of people looking for these right now. A cult classic.
