Lurid Acquerello

#37f5dd
Notes

Lurid Acquerello (#37F5DD) is a true teal 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 (172°, 90%, 59%) 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

Lurid
adjective

Latin lūridus, pale-yellow / sickly — sharing root with lūror (yellowish-pallor). As a color modifier, lurid implies a saturated-and-shocking-and-sickly-bright quality, the bright color of Penny-Dreadful-and-Pulp-Fiction sensational-cover-art bright-and-pulpy printing. Sits at the bright-and-shocking end of the grid, parallel to garish and gaudy in usage.

Acquerello
noun

The Italian word for watercolor — used for the soft, washed-out blue-greens characteristic of Italian Renaissance watercolor underpainting. Acquerello color refers to a watercolor wash on damp paper: a soft, slightly cool pale blue-green with the translucent finish of pigment-and-water on rag paper.

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.
