Valiant Clematis

#661c8f
Notes

Valiant Clematis (#661C8F) is a deep indigo 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 (279°, 67%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Valiant
adjective

Latin valēns, strong — present-participle of valēre, sharing root with English value and valor. As a color modifier, valiant implies a saturated-and-courageous-and-firm quality, the deep-rich color of Crusader-and-Knight-Templar military-religious-order vestment. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and heroic in usage.

Clematis
noun

Asian clematis (Clematis × jackmanii) — a deciduous twining-tendril vine cultivated worldwide as a garden plant, with deep-violet large four-tepalled flowers held above pinnately compound foliage. 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).
