Mellow Pewter

#1c0033
Notes

Mellow Pewter (#1C0033) is a deep indigo 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 (273°, 100%, 10%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mellow
adjective

Middle English melwe, ripe, soft — used as a color modifier since the sixteenth century for hues that read as softened by ripening or aging. Mellow gold, mellow brown: moderate-to-low saturation combined with optical warmth. Sits across the hushed and neutral buckets alongside muted.

Pewter
noun

An alloy of tin with copper, antimony, and (historically) lead — pre-industrial tableware metal of European households before china replaced it in the eighteenth century. The color refers to a Georgian pewter tankard: a soft, slightly muted gray with the satin finish of a cast and polished alloy. Cooler than bronze, warmer than silver, with the archaic-domestic weight of a metal that aged darker as households used it.

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.
