Place ½ cup of glaze into 6 small containers add tint the glaze using food coloring gel following this proportion:
Light pink - 2 red drops
Orange - 3 and 1 red drops
Yellow - 3 yellow drops
Purple - 2 red and 1 blue drops
Blue - 2 blue drops
Green - 2 blue and 3 yellow drops
Tint the remaining glaze using red food coloring to make pink.
As it cools glaze will harden, if you feel it is not flowing enough to be poured heat it in the microwave for 5 seconds or less.
To avoid a mess line a baking sheet with plastic and in the center place a container to raise the cake like a pedestal.
When the glaze stops running you can trim the excess with scissors and transfer the to a serving plate.
