Tenebrous Ciliegia
Tenebrous Ciliegia (#650B4E) 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 (315°, 80%, 22%) 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
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.
Italian for cherry (Prunus avium) — the deep-red-purple drupe of European sweet cherry, the iconic summer fruit of Tuscan and Apennine hill country. Ciliegia color refers to a freshly picked Prunus avium drupe-cluster from a Romagna orchard: a saturated, slightly cool deep magenta with the glossy finish of anthocyanin-rich cherry skin against pale flesh. Warmer than French cerise.
