Inflamed Yamabuki

#e5631e
Notes

Inflamed Yamabuki (#E5631E) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (21°, 79%, 51%) 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

Inflamed
adjective

Latin inflammātus, set on fire — past-participle of inflame. As a color modifier, inflamed implies a saturated-and-irritated-hot quality, the bright color of sun-burnt-skin and autumn-leaf high-anthocyanin pigmentation. Sits at the bright-and-warm end of the grid, parallel to fiery and flaming in usage.

Yamabuki
noun

Kerria japonica, the Japanese rose-family shrub whose bright yellow-orange flowers cover steep hillsides in late spring. Yamabuki-iro (mountain-rose color) gave Japanese its name for a saturated yellow-orange hue used in court robes and woodblock prints. The color refers to a fully open kerria flower: a saturated, slightly red-shifted yellow-orange with the satin finish of small five-petaled bloom. Warmer than canary, lighter than marigold.

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.
