Food coloring is a versatile culinary tool that can brighten a variety of dishes and condiments. A standard package of grocery-store food coloring contains four colors, red, yellow, blue and green. Intensity and pigment vary between food coloring manufacturers, so the same mixing ratio made with two different brands will create two different tones of turquoise. Creating a bright turquoise color for your next beach-themed caked or cookie icing isn't difficult but does require consistent mixing with the same brand.

  • Blue food coloring
  • Green food coloring
  • Medium mixing bowl
  • 1/4 cup mixing base (batter, frosting, liquid etc.)
  • Piece of paper
  • Pencil

Start with 1/4 cup of your mixing base in a medium mixing bowl. Use this sample as your test batch to determine the shade of turquoise you want. The high concentration of pigment in food coloring means you cannot get an accurate representation of your final turquoise shade without mixing in a base food.

Squeeze four drops blue food coloring and one drop green food coloring onto the mixing base in the bowl. Write down the color ratio so when you need to recreate the same turquoise tone in a larger quantity, you know to use three parts blue and one part green.

Stir vigorously until the color is blended evenly throughout the base. If you are satisfied with that color, replicate that same ratio as necessary in a larger quantity of mixing base. To adjust the tone of turquoise, add one drop of green or blue depending on your preference and mix thoroughly and repeat as necessary. Prevent over coloring by adding only one drop at a time and recording the total number of drops per color each time you add more
