Smooth Pyrite

#91711e
Notes

Smooth Pyrite (#91711E) is a deep amber 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 (43°, 66%, 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Pyrite
noun

An iron sulfide mineral — fool's gold — whose brassy yellow metallic luster has fooled prospectors since the California Gold Rush. Mined principally in Spain (Rio Tinto), Peru, and Italy. The color refers to a polished pyrite cube: a saturated, slightly cool deep gold with the metallic finish of crystallized iron sulfide.

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.
