Using Natural Food Colorings To Get the Same Frosting Look Shown Here: To get the same exact coloring that is shown in these pictures, follow the frosting recipe I give in this post, but instead of the milk, use a mix of
natural purple and natural teal food colorings (about half of each; both can be made using the
red cabbage method). Then once you have your light bluish purple frosting base, swirl in about 1 to 2 teaspoons of
natural blueberry food coloring for a streaked effect.
