Animated Dumortierite

#668cfd
Notes

Animated Dumortierite (#668CFD) 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 (225°, 97%, 70%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Animated
adjective

Latin animātus, given-life — past-participle of animāre, derived from anima (soul, breath). As a color modifier, animated implies a saturated-and-life-given quality where the hue carries visual movement-and-vitality. Sits at the bright-and-active end of the grid, parallel to spirited and lively in usage.

Dumortierite
noun

An aluminum-borate-silicate mineral — saturated deep blue, mined principally in Madagascar, Brazil, and Nevada. Used as ornamental stone and porcelain manufacturing additive. The color refers to a polished dumortierite cabochon: a saturated, slightly cool deep blue with the matte finish of opaque silicate mineral.
