Buffered Beryl

#66817b
Notes

Buffered Beryl (#66817B) is a true teal 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 (167°, 12%, 45%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buffered
adjective

Old French buffer, to soften the impact — past-participle of buffer. As a color modifier, buffered implies a hushed-and-cushioned-and-impact-reduced quality where the hue carries the visual register of edge-eased-and-impact-softened design-element. Sits at the hushed-and-soft end of the grid, parallel to cushioned and softened in usage.

Beryl
noun

The mineral Be₃Al₂(SiO₃)₆ — the gem family that includes emerald (chromium-tinted), aquamarine (iron-tinted), and morganite (manganese-tinted). The color beryl refers to the transparent yellow-green variety heliodor or pale common beryl: a soft, slightly muted yellow-green with the high refractive index of a faceted gem. Cleaner than sage, lighter than emerald, with the gem-trade specificity of a single mineral name.
