Purple and orange create a color known as burnt sienna when mixed together. Burnt sienna is a mud-like color that has a brown hue, according to Crayola.
Orange and purple are secondary colors on the color wheel, meaning they are created by mixing two primary colors. Orange is created by mixing the primary colors red and yellow. Purple is created by mixing the primary colors blue and red. Mixing purple and orange together creates various hues of brown depending on the amount of orange and purple used. Adding more orange brightens the shade of brown due to the red and yellow primary colors. Adding additional purple darkens the shade of brown due to the red and blue primary colors.
