Pale Calcite

#97acb2
Notes

Pale Calcite (#97ACB2) 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 (193°, 15%, 65%) places it in the muted 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

Pale
adjective

From the Latin pallidus, pale, wan — used as a color modifier since the medieval period for hues that read as low-saturation and high-light. Pale pink, pale yellow: low saturation combined with high lightness. Sits at the pale-bucket center alongside light and soft.

Calcite
noun

CaCO₃ calcium-carbonate mineral — the principal mineral of limestone-and-marble, mined principally in Italian-Carrara and English-Cotswold-quarries. Calcite color refers to a freshly cleaved Iceland-spar calcite-crystal rhomb face: a pale cool gray with the glassy finish of trigonal-system calcium-carbonate with the characteristic calcite birefringence (double-refraction).
