Plumbed Heliconia

#4c0241
Notes

Plumbed Heliconia (#4C0241) 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 (309°, 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

Plumbed
adjective

Latin plumbum, lead — past-participle of plumb (to measure depth with a lead-weighted line). As a color modifier, plumbed implies a deep-and-cool quality measured-to-its-fullest-depth, the dark cool-gray of lead-and-pewter metallic surfaces. Sits at the deep-and-cool end of the grid, parallel to fathomless with metallic register.

Heliconia
noun

Central- and South-American lobster-claw (Heliconia rostrata) — a tropical Heliconiaceae perennial cultivated worldwide for its pendulous rostrate-bracted inflorescences in deep-magenta-and-yellow. Heliconia color refers to a fully developed Heliconia rostrata pendulous inflorescence: a saturated, slightly cool deep magenta with the matte finish of waxy bract-clusters. Named for Mount Helicon, the muses' Greek-mythological mountain.

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.
