Scorching Lazuli

#57fefb
Notes

Scorching Lazuli (#57FEFB) 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°, 99%, 67%) 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

Scorching
adjective

Old English scorcnian, to dry up — present-participle of scorch. As a color modifier, scorching implies a saturated-and-burning-hot quality, the bright color of Mojave-Desert-and-Death-Valley mid-afternoon high-temperature surface-emission. Sits at the bright-and-warm end of the grid, parallel to searing and sizzling 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
