Flaming Cardoon

#3df9db
Notes

Flaming Cardoon (#3DF9DB) 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 (170°, 94%, 61%) 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

Flaming
adjective

Old French flamme, flame — present-participle of flame. As a color modifier, flaming implies a saturated-and-fire-and-bright-color quality, the bright color of autumn-Maple-and-Oak deciduous-foliage fall-color and Yule-log fire emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.

Cardoon
noun

Cynara cardunculus, the Mediterranean thistle — relative of the globe artichoke (C. cardunculus var. scolymus) — with deeply lobed silver-green foliage and architectural form. The color refers to mature cardoon foliage in a kitchen garden: a soft, slightly cool silver-green-blue with the matte finish of large pinnately lobed leaves.

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.
