If you know someone who has a passion for the color turquoise, little could be more appropriate for a birthday than a cake covered in that color. Gather some simple ingredients and mix up the frosting for a cake your friends, family and guests will find uniquely appealing.

Spoon one batch of white frosting into a large mixing bowl.

Put 6 drops of sky blue food coloring into the frosting. Add 1 drop of lemon yellow food coloring.

Mix the frosting and food colorings together until they are entirely uniform in color. The color will be a light turquoise color. If you like this color, frost the cake. If the color is too light, darken it with more coloring.

Continue adding more food coloring until it is dark enough. Add 6 drops of sky blue and 1 drop of lemon yellow every time, then stir to test the color.

Warning

Don't vary the recipe of 6 drops blue to 1 drop yellow or the color will come out some other shade beside turquoise.
