When it comes to mixing colors with watercolors, there are a limited number of colors that can be made by combining just two colors. However, by adding a third color to the mix, the number of colors that can be created expands significantly. So, if you're looking to create the color purple, you'll need to mix together the colors red and blue.
The ratio of colors that you'll need to mix will depend on the shade of purple that you're looking to create. For a lighter purple, you'll want to use more blue than red. For a darker purple, you'll want to use more red than blue. And for a more vibrant purple, you'll want to use an equal amount of both colors.
To create your purple color, start by wetting your brush with water. Then, add a small amount of red paint to your brush and mix it with the water. Next, add a small amount of blue paint to the brush and mix it with the water. Continue adding and mixing colors until you've achieved the desired shade of purple.
Once you're happy with the color, you can begin painting with it. Remember, watercolors dry lighter than they appear when wet
