Even Kelp

#3c663a
Notes

Even Kelp (#3C663A) is a deep green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (117°, 28%, 31%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Even
adjective

Old English efen, flat, equal — used as a color modifier since the medieval period for hues that read as uniformly distributed across a surface. Even gray, even tan: the implication is moderate saturation combined with optical uniformity. Sits at the crisp-bucket center alongside steady and balanced.

Kelp
noun

Large brown algae of the order Laminariales — the giant Macrocystis pyrifera of California's coast and the smaller Laminaria digitata of British shores. Kelp color refers to fresh kelp washed up on a Pacific beach at low tide: a deep, slightly muted dark green-brown with the satin finish of marine alga.
