Steadfast Achimenes
Steadfast Achimenes (#8E116B) 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 (317°, 79%, 31%) 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
Old English stede-fæst, fixed in place — sharing root with German stetig. As a color modifier, steadfast implies a saturated-and-unwavering quality where the hue maintains its visual character without modulation. Sits at the bold-and-firm end of the grid, parallel to unwavering and firm in usage.
Mexican magic flower (Achimenes longiflora) — a Gesneriaceae tuberous-rhizome perennial native to Central American cloud-forest understory, with deep-magenta tubular flowers that bloom in summer and dormant rhizomes in winter. Achimenes color refers to a fully opened Achimenes longiflora tubular flower: a saturated, slightly cool deep magenta with the velvet finish of fresh fused-petaled tubular corolla. Greek achimenes means winter-tender.
