Brown is a color made by mixing red, yellow, and black or by darkening orange. It is the color of many natural things like soil, tree trunks, and some animals’ fur.
From Old English “brūn,” meaning “brown, dark, or shining,” used for dark colors and sometimes for polished metal. Related to German “braun” and other Germanic words for the same color.
Brown is special because there’s no single wavelength of light for it—your brain invents brown by mixing signals. When you see brown, you’re actually seeing a trick your visual system plays with dimmed oranges and surrounding colors.
