Centered Hampton

#1b8a30
Notes

Centered Hampton (#1B8A30) 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 (131°, 67%, 32%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Centered
adjective

Latin centrum, center — past-participle of center. As a color modifier, centered implies a saturated-and-grounded-and-balanced quality where the hue occupies the visual center of its palette without drift. Sits at the bold-and-balanced end of the grid, parallel to poised and grounded.

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.
