Brown colors are dark or muted shades of reds, oranges, and yellows on the RGB and CMYK color schemes. In practice, browns are created by mixing two complementary colors from the RYB color scheme (combining all three primary colors).

Darker shades of blue include ultramarine, cobalt blue, navy blue, and Prussian blue; while lighter tints include sky blue, azure, and Egyptian blue (for a more complete list see the List of colours).
