Mixing food coloring creates new colors to expand your color palette for food or craft projects. Making new colors with food coloring also provides a learning activity for kids. The Brigham Young University website shows how adding food coloring to vases of water for white flowers dyes the flowers. Food coloring kits usually come with red, yellow, green and blue. The University of Wisconsin Green Bay website features an artist's color wheel that displays the relationships between primary and secondary colors. Learning color relationships allows you to mix food coloring with confidence.
Combine an equal quantity of red and blue food coloring to make purple. Add more red to make magenta or scarlet and more blue to make a dark grape purple.
Mix yellow and red food coloring to make orange. For a dark, sunset or blood orange, add more red. For a lighter, pumpkin orange, use more yellow.
Add blue food coloring to green food coloring a drop at a time to create a new blue-green or turquoise color.
Add yellow food coloring a drop at a time to green food coloring to make spring green and lime green colors.
Create dark gray or black, depending on your food coloring, by mixing equal parts of red and blue, and then adding green drop by drop to reach the desired color.
