Pithed Glacier

#0a1d1c
Notes

Pithed Glacier (#0A1D1C) is a deep cyan 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 (177°, 49%, 8%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pithed
adjective

Old English piþa, pith / inner stalk — past-participle of pith. As a color modifier, pithed implies a deep-and-cored-out quality where the visual surface has been excavated to reveal interior darkness. Sits at the deep-and-architectural end of the grid, parallel to hollowed and cored.

Glacier
noun

A compressed mass of ice that has accumulated over decades or centuries — Alpine, Andean, Patagonian, polar. The color refers to the exposed face of a clean glacier where compression has driven out the air: a soft, very pale blue-green with the optical clarity of dense ice. Lighter than aqua, cooler than seafoam, with the high-altitude weight of a landform now retreating across most of the planet.
