Sturdy Corsica
Sturdy Corsica (#1A9660) is a true 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 (154°, 70%, 35%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.
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.
