How to Make Purple with Food Coloring
Creating purple with food coloring is straightforward. Here’s a step-by-step guide to help you achieve the perfect shade:
-
Gather Your Supplies: You will need red and blue food coloring, as well as a mixing bowl or small cup for combining the colors.

When mixing colors, it’s helpful to understand basic color theory. Red and blue are primary colors, and when combined, they create secondary colors like purple. The exact shade of purple depends on the ratio of red to blue.
| Color | Mixing Ratio | Result |
|---|---|---|
| Light Purple | 3 parts red, 1 part blue | Lavender or lilac shade |
| Medium Purple | Equal parts red and blue | Classic purple |
| Dark Purple | 1 part red, 3 parts blue | Deep violet |
