Color Jam

From BoardGameGeek:

Color Jam is puzzley coloring game of happy accidents. Pick 6 colors to cooperatively color your picture with, pick some goals, then start coloring from two star spaces. You can only color spaces touching a colored space, and you can only use the crayon in the slot matching the space's number. When you're done coloring, you place your crayon back in the 6th slot and move all other crayons up. The result is a challenging puzzle that'll have you coloring off the rails and into a color jam.
