Creating brown paint is a simple process. Usually it entails mixing red, yellow and a touch of blue. You can also make brown by mixing gray with a primary color and two secondary colors from the color wheel. When these three colors mix, you get a darker brown that's handy in painting areas that are shadowed or in less light than the rest of the painting.
