Earnest Beryl
Earnest Beryl (#3AA566) 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 (145°, 48%, 44%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.
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.
