Healthful Frock Teal

#30b197
Notes

Healthful Frock Teal (#30B197) 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 (168°, 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

Healthful
adjective

Old English hǣlth, health — adjectival suffix -ful. As a color modifier, healthful implies a clear-and-vital-and-wholesome quality where the hue carries the visual register of fresh-air-and-sunlight outdoor health-promoting environment. Sits at the crisp-and-wholesome end of the grid, parallel to salubrious and wholesome in usage.

Frock
modifier

Old French froc, monk's-habit-or-loose-garment. As a color modifier, frock implies a monk's-habit-and-pinafore-and-day-frock quality, the visual register of Benedictine-monk's-frock-and-Edwardian-day-frock hand-monk's-habit-and-pinafore-and-day-frock Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore frock-and-monk's-habit-and-pinafore surfaces under Benedictine-monk's-frock-and-Edwardian-day-frock-and-pinafore Cluny-Abbey-and-Edwardian-tea-room habit-and-day-dress-light. Sits at the modifier-and-textile end of the grid, parallel to gown and cope 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.
