Fiery Kuri
Fiery Kuri (#FDB64B) 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 (36°, 98%, 64%) 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
Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.
The Japanese chestnut — Castanea crenata — a culinary and ornamental tree across Japan. Kuri-iro (chestnut color) refers to the warm brown of roasted chestnut shells. The color refers to freshly roasted kuri in autumn: a soft, slightly muted warm brown with the matte finish of toasted nut. Drier than caramel, warmer than walnut.
