Sturdy Patagonia

#3857b4
Notes

Sturdy Patagonia (#3857B4) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (225°, 53%, 46%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sturdy
adjective

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.

Patagonia
noun

The southern South American region — Chile and Argentina — and the saturated deep blue of Lago Argentino, Perito Moreno Glacier, and the Patagonian summer sky. Patagonia refers to Lago Argentino at midday: a saturated, slightly cool deep blue with the optical depth of glacier-fed Patagonian lake.
