Mud Colors
"Mud" names describe the dark, earthy yellows, browns and olive greens of wet soil. The register lists 7 color names containing "Mud" or "Muddy". Most come from the online color survey run by the webcomic xkcd, where people named random colors in their own words: Mud Brown, Mud Green, Muddy Brown, Muddy Green and Muddy Yellow. The list sits in the yellow and orange families, where low lightness turns yellow into olive and orange into brown, and most entries are dark. Saturation is higher than you might expect: what makes these colors look muddy is darkness, not greyness. Muddy Waters is the lightest, a sandy tan.
