Sterile Diana Teal

#3cb39d
Notes

Sterile Diana Teal (#3CB39D) 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 (169°, 50%, 47%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Diana
modifier

Latin Diana, Roman-goddess-of-moon-and-hunt. As a color modifier, diana implies a Roman-goddess-and-moon-and-hunter-and-virgin quality, the visual register of Roman-Diana-and-Ephesian-Artemis hand-Roman-goddess-and-moon-and-hunter-and-virgin Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi diana-and-Roman-goddess-and-moon-and-hunter surfaces under Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi Aventine-Hill-and-Nemi-grove moonlit-grove-light. Sits at the modifier-and-myth end of the grid, parallel to luna and hera in usage.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.

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.
