Abundant Sugilite
Abundant Sugilite (#8C3CC7) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (275°, 55%, 51%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin abundāre, to overflow — present-participle of abound. As a color modifier, abundant implies a saturated-and-plentiful quality where the hue carries surplus visual richness beyond minimum requirement. Sits at the bold-and-saturated end of the grid, parallel to plentiful and bountiful.
A manganese-bearing cyclosilicate gem first described in 1944, with major sources in South Africa's Wessels Mine. The color refers to a polished sugilite cabochon: a saturated, slightly red-shifted deep purple with the matte finish of opaque mineral. Cooler than amethyst, warmer than tanzanite, with the gem-trade rarity of a stone produced commercially from one principal mine and priced accordingly.
