Rich Hampton

#317112
Notes

Rich Hampton (#317112) is a deep green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (100°, 73%, 26%) places it in the balanced 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Hampton
noun

The English Tudor palace at Hampton Court — and the saturated green of its famous Hampton Court Maze, the oldest surviving hedge maze in the world (planted 1690). Hampton refers to a yew-hedge in the Hampton Court Maze: a deep, slightly cool dark green with the matte finish of densely clipped yew.
