Smoky Tyre

#3a155a
Notes

Smoky Tyre (#3A155A) 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 (272°, 62%, 22%) 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

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

Tyre
noun

Ancient Phoenician city on the Lebanese coast — the industrial-scale production site for Tyrian purple (the μύρεξ shellfish-dye that ruled Mediterranean elite color codes from 1500 BCE to 1453 CE). Tyre color refers to a Tyre-produced Tyrian purple dyed Roman toga picta: a saturated, slightly cool deep violet with the matte finish of multi-bath Bolinus brandaris shellfish dye on woolen toga cloth.

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.
