Sanitary Joy Teal

#30b09d
Notes

Sanitary Joy Teal (#30B09D) is a true teal 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 (171°, 57%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sanitary
adjective

Latin sānitās, health — adjectival suffix -ary. As a color modifier, sanitary implies a clear-and-clean-and-medical quality, the crisp color of Bauhaus-and-Modern clinical-and-hospital interior-architecture white-tile-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to hygienic and sterile in usage.

Joy
modifier

Latin gaudia, delights. As a color modifier, joy implies a bright-and-radiant-and-uplifted quality, the visual register of Provençal-troubadour-and-Florentine-Carnival-joy hand-bright-and-radiant-and-uplifted Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa joyful-and-bright-and-radiant-and-uplifted surfaces under Provençal-troubadour-and-Florentine-Carnival-and-Renaissance-festa banner-and-procession-and-piazza festival-day-light. Sits at the modifier-and-mood end of the grid, parallel to bliss and glee 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.
