Symmetrical Amazonite

#139c81
Notes

Symmetrical Amazonite (#139C81) is a deep teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (168°, 78%, 34%) places it in the highly saturated band at a dark 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Symmetrical
adjective

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Amazonite
noun

A blue-green variety of microcline feldspar — colored by trace lead and water in its crystal structure. Mined since ancient times in the Russian Urals and now in Colorado, Madagascar, and Brazil. The color refers to a polished amazonite cabochon: a soft, slightly muted blue-green with the cloudy translucency of feldspar. Cooler than jade, warmer than cerulean, with the mineral-trade specificity of a stone named for the Amazon basin where it doesn't actually occur.

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.
