Truthful Saint-Tropez

#37bcc2
Notes

Truthful Saint-Tropez (#37BCC2) is a true cyan 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 (183°, 56%, 49%) 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

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest in usage.

Saint-Tropez
noun

The French Riviera resort — and the saturated blue of the Côte d'Azur coast at Pampelonne Beach and Plage de la Bouillabaisse. Saint-Tropez color refers to mid-summer Côte d'Azur water: a saturated, slightly cool deep blue with the optical clarity of warm Mediterranean coast.
