Combustive Bath

#febb39
Notes

Combustive Bath (#FEBB39) is a true amber 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 (40°, 99%, 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.

Bath
noun

The English Roman-spa city — and the cream-tan of Bath stone, the oolitic limestone used in the city's Georgian terraces and the Royal Crescent. The color refers to the south-facing facade of the Royal Crescent at midday: a soft, slightly cool warm cream-tan with the matte finish of Bath stone. Lighter than Cotswold, cooler than honey.

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.
