Sharp Glacier

#31e6ee
Notes

Sharp Glacier (#31E6EE) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (183°, 85%, 56%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Sharp
adjective

Old English scearp, cutting, pointed — applied metaphorically to color since the seventeenth century for hues that read as definite and edge-defined. Sharp red, sharp green: the implication is saturation combined with high-contrast crispness. Sits in the bright-bucket center alongside crisp and clear, with a slightly more incisive edge.

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.
