Abundant Liatris

#663fc5
Notes

Abundant Liatris (#663FC5) 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 (257°, 54%, 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

Abundant
adjective

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.

Liatris
noun

North American prairie blazing star (Liatris spicata) — its dense vertical spike of disk-flowers blooms top-down in late summer across midwestern tallgrass prairie. Liatris color refers to a fully bloomed Liatris spicata spike on a Wisconsin prairie remnant: a saturated, slightly cool deep blue-violet with the velvet finish of fresh disk-flowers. Slightly warmer than Verbena and cooler than Lythrum salicaria.
