The last level is simpler than that, Sam. Dip it in Red, put the mask on, dip it in thinner, take the mask off, rotate 7 times, dip it in thinner again, take the mask off, put the hat on, dip it in red, then thinner, remove the hat.
Very easy. All gold, only had to redo one level to get it right. If you understand the math behind map coloring, finding the places to start is pretty easy.
