Lavish Tanzanite

#4c39ad
Notes

Lavish Tanzanite (#4C39AD) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (250°, 50%, 45%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lavish
adjective

Old French lavasse, downpour — sharing root with laver (to wash). As a color modifier, lavish implies a saturated-and-extravagant quality where the hue spills over its visual boundaries with luxurious pigmentation. Sits at the bold-and-saturated end of the grid, parallel to opulent and sumptuous 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.
