Cottony Heliotrope

#a0a3bc
Notes

Cottony Heliotrope (#A0A3BC) is a true blue 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 (234°, 17%, 68%) places it in the muted 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cottony
adjective

Arabic qutn, cotton — adjectival suffix -y. As a color modifier, cottony implies a pale-and-fluffy-and-soft quality, the pale color of Mississippi-Delta-and-Egyptian-Nile-Delta freshly-picked-and-ginned cotton-fiber-and-boll soft-and-fluffy textile-finish. Sits at the pale-and-soft end of the grid, parallel to fluffy and fleecy in usage.

Heliotrope
noun

The genus Heliotropium — the cherry pie plant, named in Greek for its supposed habit of tracking the sun (heliotropism). The color refers to a fresh garden heliotrope cluster in late summer: a saturated, slightly red-shifted deep purple-blue with the matte finish of densely packed forget-me-not-style flowers. Cooler than mauve, warmer than indigo, with the perfumed weight of a flower whose vanilla-cherry scent fills a greenhouse.
