Punchy Alkanet

#8c183b
Notes

Punchy Alkanet (#8C183B) is a deep red 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 (342°, 71%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

Alkanet
noun

Anchusa tinctoria, the Mediterranean borage whose roots yield a red dye used since classical times for cosmetics and wine coloring. The color refers to fresh alkanet-dyed wool: a saturated, slightly cool deep red with the matte finish of plant-and-mordant dye. Cooler than madder, deeper than crimson.

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.
