Combustive Daylily

#fd8a3a
Notes

Combustive Daylily (#FD8A3A) is a true orange 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 (25°, 98%, 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Combustive
adjective

Latin combūstus, burnt — adjectival suffix -ive, derived from com-burere (to burn-up). As a color modifier, combustive implies a saturated-and-burning-active quality, the bright color of blast-furnace-and-foundry combustion-chamber emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.

Daylily
noun

The genus Hemerocallisday-beauty in Greek — perennial lily-relatives whose individual flowers bloom for a single day before wilting. The color refers to a fresh orange daylily H. fulva on a roadside: a saturated, slightly red orange with the satin finish of trumpet-shaped flower. Brighter than tangerine, with the ephemeral weight of a flower whose bloom lasts hours.

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.
