How to Make Turquoise Food Coloring

Learn how to make a beautiful shade of turquoise food coloring for all your baking or craft needs by following these simple instructions below.

Note: This food coloring can be used in a variety of recipes or crafts, but to best highlight the rich shade of turquoise, we're using buttercream frosting as our visual “canvas."

  • The drop stopper will help you count the drops of food dye. Alternatively, if you don't have access to a drop stopper, you can try to count the drops added individually. Another good way to measure the drops needed is by thinking that 100 drops of food colouring is equal to about 1 teaspoon.

Mix the Colors

Begin by mixing the blue and green food dyes into the base that you wish to color.

To make a turquoise shade, add 3 drops of green food coloring to every 5 drops of blue food coloring. Mix to combine the use as required.

The drops of dye needed will slightly vary depending upon the type and quantity of base that you are coloring. Test the strength of the color as you go. It's quite easy to over-color and difficult to lighten the shade after the food dye has been added.
