Drawn Glacier

#66bbb9
Notes

Drawn Glacier (#66BBB9) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (179°, 38%, 57%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drawn
adjective

Old English dragan, to draw — past-participle of draw. As a color modifier, drawn implies a clear-and-line-and-mark quality, the crisp color of Old-Master-and-Modernist hand-drawn studio-and-life-class observational-drawing graphite-and-charcoal lines. Sits at the crisp-and-incised end of the grid, parallel to etched and drafted in usage.

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.
