Dappled Lazuli

#99aeb5
Notes

Dappled Lazuli (#99AEB5) 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 (195°, 16%, 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dappled
adjective

Old Norse depill, spot / pool — past-participle of dapple. As a color modifier, dappled implies a pale-and-mottled-and-light-and-shadow-spotted quality, the pale color of summer-orchard sun-through-leaves dappled-light-and-shadow ground-pattern surface. Sits at the pale-and-soft end of the grid, parallel to speckled and mottled in usage.

Lazuli
noun

Passerina amoena, the lazuli bunting — a North American songbird whose males display saturated deep-blue plumage with white wing bars and chestnut breasts. Named for the gemstone (lapis lazuli) the bird's plumage resembles. The color refers to a male lazuli bunting in breeding plumage: a saturated, slightly cool deep blue.
