Color each of the boxes in this grid either Red, Yellow

or Blue. Some of the boxes have clues like R2, Y3 or

B0. These clues mean that the box has 2 red neighbors,

3 yellow neighbors, or no blue neighbors. Two boxes

are neighbors if they share an edge, not just a corner.

All of the boxes of each color must be connected.
