6 insert set to color the three inserts in the danger room: the warning insert (1) to match the spinner above it, the electric bolt (3) a more appropriate bluish color, and the BAMF insert (2) a light pink to match the art on the playfield. The remaining 3 (labeled 4-5-6 in the picture) are to color the other 3 BAMF target inserts on the playfield so they all match the playfield art as well.
