Bleak Clematis

#420447
Notes

Bleak Clematis (#420447) 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 (296°, 89%, 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.

Clematis color refers to a fully bloomed Clematis × jackmanii tepalled-flower in a Cotswold cottage garden: a saturated, slightly cool deep violet with the velvet finish of fresh broad-tepalled flat-corolla. The genus name comes from the Greek klēmatís (climbing plant).
