8×8 NaYBR

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.
