Color mixing made easier with our Color Wheels Combo. Use this set to create your customized color mixing wheels for future reference. No color wheel can be as accurate as the ones you make yourself with the media you have on hand! Please watch our video for detailed instructions. The color mixing chart is usually used for opaque media such as gouache and acrylic paints. The purpose of the chart is to practice the mixing ratios. The idea is to use just primary colors: Red, Yellow and Blue, but you can try mixing colors from each family and might find some interesting results :) For these, you will mix the colors on a palette first. rB means reddish blue, which should have more blue than red. bR on the other hand means bluish red, which should have more red than blue.
