Tomblike Violetta

#280a54
Notes

Tomblike Violetta (#280A54) 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 (264°, 79%, 18%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tomblike
adjective

Greek tymbos, tomb — adjectival suffix -like. As a color modifier, tomblike implies the deep-and-funereal-and-sepulchral quality of Etruscan-and-Egyptian rock-cut royal-tomb interiors, particularly the Valley-of-the-Kings and Cerveteri-necropolis hand-carved chamber-painting walls. Sits at the deep-and-funereal end of the grid, parallel to sepulchral and crypted.

Violetta
noun

Italian for little violet (Viola odorata) — the diminutive form of viola, also the name of Verdi's tragic heroine in La Traviata (1853). Violetta color refers to a freshly cut Viola odorata nosegay: a saturated, slightly cool deep blue-violet with the velvet finish of fresh viola petals. Richer than viola (the broader genus name) and less wisteria-warm than glicine.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
