Here is a simple worksheet for mixing paints using a color wheel:

1. Start by drawing a color wheel on a piece of paper. Divide the circle into 12 equal sections.

2. Label each section with the primary colors: red, blue, and yellow. Place these colors evenly around the circle.

3. Next, label the secondary colors: orange, green, and purple. These colors are created by mixing equal parts of two primary colors. Place them between the corresponding primary colors.

4. Finally, label the tertiary colors: red-orange, yellow-orange, yellow-green, blue-green, blue-purple, and red-purple. These colors are created by mixing equal parts of a primary color and a secondary color. Place them between the corresponding primary and secondary colors.

5. Now, it’s time to mix the paints. Start with the primary colors. Take a small amount of red paint and mix it with an equal amount of blue paint. Observe the resulting color and write it down in the section between red and blue on the color wheel.

6. Repeat the process for the other primary colors. Mix yellow and blue to create green, and mix red and yellow to create orange. Write down the resulting colors in the appropriate sections on the color wheel.

7. Next, mix the secondary colors with the primary colors adjacent to them. For example, mix orange with red to create red-orange, and mix green with yellow to create yellow-green. Write down the resulting colors in the appropriate sections on the color wheel.

8. Finally, mix the tertiary colors. For example, mix red with orange to create red-orange, and mix blue with purple to create blue-purple. Write down the resulting colors in the appropriate sections on the color wheel.

9. Once you have completed all the mixing, you can use the color wheel as a reference for future painting projects. It will help you understand how different colors can be created by mixing various combinations of primary and secondary colors.

Remember to have fun and experiment with different paint ratios to create unique colors!
