Mix with 3/4 cups of heavy cream, milk, and coconut powder. Divide the batter into 6 parts to obtain 6 colors. Mix in one part the blue dye, in another the red dye, in another the yellow. For the last three colors, add blue and yellow for green, yellow and red for orange, blue and red for purple. Pour the first color into a mold. Bake at 350 F for 10 minutes. Turn out and repeat with the second color and so on.
