Tidy Saint-Tropez

#40d1c8
Notes

Tidy Saint-Tropez (#40D1C8) 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 (176°, 61%, 54%) 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

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

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.
