Aflame Castile

#fec73f
Notes

Aflame Castile (#FEC73F) 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 (43°, 99%, 62%) 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

Aflame
adjective

Old English on-flamme, on-fire. As a color modifier, aflame implies a saturated-and-burning-bright quality, the bright color of autumn-Maple-and-Oak peak-color deciduous-foliage and Bonfire-Night large-flame fire emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.

Castile
noun

The arid central plateau of Spain — and the warm tan of Castilian sandstone and the wheat fields of La Mancha. The color refers to a Castilian meseta in late summer: a soft, slightly muted warm tan-yellow with the matte finish of dry wheat-and-soil landscape. Drier than honey.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
