Forceful Tsutsuji
Forceful Tsutsuji (#A9177F) 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°, 76%, 38%) 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.
Etymology
Old French force, strength — adjectival suffix -ful. As a color modifier, forceful implies a saturated-and-vigorous quality where the hue exerts visual force on its substrate. Sits at the bold-and-saturated end of the grid, parallel to mighty and commanding in tone.
Japanese 躑躅, azalea (Rhododendron indicum and R. obtusum) — a beloved spring-flowering shrub of Japanese gardens, particularly the deep-magenta kirishima-tsutsuji cultivars from Kagoshima's Mt. Kirishima. Tsutsuji color refers to a fully bloomed kirishima-tsutsuji terminal truss in a Kyoto temple garden: a saturated, slightly cool deep magenta with the velvet finish of fresh five-petaled bell-flowers in dense terminal clusters.
