Tan is a versatile color that can be used to create a variety of looks, from natural to dramatic. While there are many ways to create tan with food coloring, the most common method is to combine yellow, red, and blue food coloring.
The proportions of each color will vary depending on the desired shade of tan. For a light tan, use more yellow and less red and blue. For a darker tan, use more red and blue and less yellow. It is important to start with small amounts of each color and gradually add more until the desired shade is achieved.
