Lush Drear Tanzanite

#3b0c67
Notes

Lush Drear Tanzanite (#3B0C67) 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 (271°, 79%, 23%) 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

Lush
adjective

Middle English lush, possibly from lascious, lascivious — a word that drifted from sensual ripeness toward visual abundance. Used as a color word since the eighteenth century for the saturated greens of well-watered foliage and the deep saturated jewel tones of velvet upholstery. Used across the deep and bold buckets where the hue is simultaneously dark and vivid.

Drear
modifier

Old English drēor, gore-and-sorrow. As a color modifier, drear implies a bleak-and-cheerless-and-sorrowful quality, the visual register of Brontë-moorland-and-Hardy-heath-drear hand-bleak-and-cheerless-and-sorrowful Brontë-moorland-and-Hardy-heath-and-Wuthering drear-and-bleak-and-cheerless-and-sorrowful surfaces under Brontë-moorland-and-Hardy-heath-and-Wuthering rain-swept-and-low-cloud-and-empty-vista Yorkshire-and-Wessex-light. Sits at the modifier-and-mood end of the grid, parallel to bleak and gloom in usage.

Tanzanite
noun

A blue-violet variety of zoisite — discovered in 1967 in a single small area of northern Tanzania near Mount Kilimanjaro and marketed by Tiffany & Co. shortly after. The color refers to a faceted tanzanite cut to maximize its strong pleochroism: a saturated, slightly violet-shifted deep blue-purple with the gem's signature internal life. Cooler than amethyst, warmer than iolite, with the gem-trade specificity of a stone that occurs in exactly one place on Earth.

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.
