1. Gather your ingredients: To make brown food coloring, you will need red, blue, and yellow food coloring, along with a small container and a toothpick or dropper for mixing.

2. Start with primary colors: Add equal amounts of red, blue, and yellow food coloring in the container. Begin with just one drop of each color to prevent over-saturating your dish.

3. Mix the colors: Use the toothpick or dropper to mix the colors together in the container. As you mix, you’ll notice that the combination of primary colors creates a brown shade.

4. Adjust for desired shade: If you want a lighter brown shade, add more yellow food coloring. For a darker brown shade, add more blue and red until you achieve the desired color.

5. Test your color: Before adding the new brown food coloring to your dish, test it on a small piece of white paper or plate to see how it looks under normal lighting conditions.

6. Add the brown food coloring to your dish: Once you’re satisfied with the color, add it into your dish a little at a time, continuously stirring to evenly distribute the color.

7. Adjust as needed: If you find that the shade of brown is still too light or too dark after adding it into your dish, gradually adjust by adding more of the appropriate primary colors until you reach the perfect brown shade.

8. Store leftover food coloring: If you’ve made more brown food coloring than needed for your current dish, store it in an airtight container for future use.

9. Enjoy your creation: With your perfect shade of brown food coloring completed and added to your dish, enjoy sharing it with family and friends!
