Placid Kumquat

#8f3b1c
Notes

Placid Kumquat (#8F3B1C) is a deep orange 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 (16°, 67%, 34%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Placid
adjective

Latin placidus, gentle / quiet — derived from placēre (to please). As a color modifier, placid implies a clear-and-unruffled quality where the hue carries the visual register of mirror-smooth lake-surface in windless mid-morning. Sits at the crisp-and-calm end of the grid, parallel to serene and peaceful in usage.

Kumquat
noun

Citrus japonica, the small East Asian citrus eaten whole — sweet rind, tart pulp. The color refers to a fresh Cantonese-region kumquat in early winter: a saturated, slightly red orange with the satin finish of small citrus rind. Warmer than mikan, deeper than mandarino. The smallest cultivated citrus.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
