Pleasant Crown Mint

#51d1b6
Notes

Pleasant Crown Mint (#51D1B6) 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 (167°, 58%, 57%) 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

Pleasant
adjective

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Crown
modifier

Latin corōna, garland / crown. As a color modifier, crown implies a royal-headpiece-and-coronation quality, the visual register of British-Imperial-State-Crown-and-French-Crown-Jewel hand-set jeweled-and-velvet-and-gilt royal-and-Imperial-coronation surfaces under Imperial-State-Crown-and-French-Crown-Jewel royal-and-Imperial coronation-day light. Sits at the modifier-and-cultural end of the grid, parallel to throne and coronet in usage.

Mint
noun

The genus Mentha — peppermint, spearmint, apple mint, water mint — the cooling herb whose menthol gives it that quality at the molecular level. The color refers to fresh peppermint leaves before drying: a clean, slightly cool green with the matte finish of trichome-rich leaf surface. Lighter than basil, cooler than parsley, with the mojito-and-Pimm's association of a herb tied to summer drinks across two continents.
