Heavy Liatris

#63489b
Notes

Heavy Liatris (#63489B) 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 (260°, 37%, 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

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.

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.
