Caliginous Punch

#4a0237
Notes

Caliginous Punch (#4A0237) is a deep magenta 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 (316°, 95%, 15%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Caliginous
adjective

Latin cālīginōsus, misty / dark — derived from cālīgō (mist, gloom). As a color modifier, caliginous implies an obscured, dimmed, slightly-cool-shifted quality where the hue is veiled by darkness or atmospheric fog. Sits at the deep-and-veiled end of the grid, between murky and tenebrous in usage.

Punch
noun

A bright pink-red color named for the surface of a fruit punch — particularly the Tahitian-style punches of mid-century cocktail culture and the brand-name Hawaiian Punch whose color was a signature. The color refers to a saturated, slightly cool red-pink: brighter than fuchsia, warmer than rose, with the mid-century-tropical weight of a color tied to a specific decade of American cookout entertaining.

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.
