Clear Corsica

#15844f
Notes

Clear Corsica (#15844F) is a deep teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (151°, 73%, 30%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Corsica
noun

The French Mediterranean island — and the saturated blue-green of Corsican calanques (rocky coves) at Calanche de Piana and Bonifacio. Corsica refers to a Bonifacio cove at midday: a saturated, slightly cool deep blue-green with the optical clarity of cold Tyrrhenian Sea water.
