Grounded Lythrum

#a7107c
Notes

Grounded Lythrum (#A7107C) is a true 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 (317°, 83%, 36%) places it in the highly saturated band at a mid 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.

Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Lythrum
noun

Lythrum salicaria, purple loosestrife — a Eurasian native wetland perennial whose deep-magenta vertical spikes carpet European marsh-and-fen habitats and have aggressively naturalized across North American wetlands. Lythrum color refers to a fully bloomed Lythrum salicaria terminal spike on a Norfolk Broads fen: a saturated, slightly cool deep magenta with the velvet finish of dense small six-petaled flowers. Greek lýthron (clotted blood).
