2) Add fondant
Split white fondant into four balls. Color one ball blue and the others red, violet and orange. Knead until color is evenly distributed. Use 9 in. fondant roller with pink guide rings to roll out orange, purple, red and blue fondant, separately, about 1/16 in. thick. Cut fondant into mask shapes, 4 in. long x 1 1/2 in. wide. Position strips on iced brownies.
