Eclipsed Antarctic

#15203a
Notes

Eclipsed Antarctic (#15203A) is a deep azure 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 (222°, 47%, 15%) 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.

Antarctic
noun

The continent at Earth's southern pole — and the saturated deep blue of Antarctic polynyas (open-water gaps in the sea ice) and the deep blue beneath fresh-calved icebergs. Antarctic refers to a polynya in the Ross Sea: a saturated, slightly cool deep blue with the optical depth of cold polar seawater.
