Tenebrous Strobilanthes

#581569
Notes

Tenebrous Strobilanthes (#581569) 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 (288°, 67%, 25%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tenebrous
adjective

Latin tenebrōsus, full of darkness — derived from tenebrae (the deepening shadows of evening prayer service). As a color modifier, tenebrous implies a literary-poetic register for deep-shadowed darkness, where the hue is overwhelmed by ambient gloom. Sits at the deep-and-cool end of the grid, near Stygian but with painterly-baroque connotations.

Strobilanthes
noun

Asian Persian shield (Strobilanthes dyerianus) — a Burmese-native evergreen shrub cultivated worldwide for its iridescent violet-and-silver leaf coloration. Strobilanthes color refers to a Strobilanthes dyerianus leaf upper surface in raking light: a saturated, slightly cool deep violet with the iridescent satin finish of structurally colored cuticular leaf surface. The genus name comes from the Greek stróbilos (cone) and anthos (flower).
