Suffocating Borscht

#640357
Notes

Suffocating Borscht (#640357) is a deep violet 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 (308°, 94%, 20%) 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

Suffocating
adjective

Latin suffocāre, to choke — present-participle of suffocate. As a color modifier, suffocating implies a deep-and-overwhelming-and-pressing quality where the hue overwhelms the eye's capacity to discern surface detail. Sits at the deep-and-overwhelming end of the grid, parallel to smothering with breath-restricting register.

Borscht
noun

Eastern European beet-soup — particularly the Ukrainian and Polish bórshch and Russian borshch, made from Beta vulgaris roots and cabbage in a deep-magenta broth. Borscht color refers to a freshly served bowl of Ukrainian bórshch with a sour-cream swirl: a saturated, slightly cool deep magenta with the matte finish of betalain-pigmented beet broth. Slightly warmer than Belarusian barszcz.

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.
