Eclipsed Patagonia

#133b87
Notes

Eclipsed Patagonia (#133B87) is a deep azure 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 (219°, 75%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Eclipsed
adjective

Greek ékleipsis, abandonment — past-participle of eclipse. As a color modifier, eclipsed implies the deep occulting darkness of a celestial-body-blocked light-source, where umbral-and-penumbral shadows fall on the hue. Sits at the deep-and-cool end of the grid, parallel to occluded with astronomical connotation.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
