Hot Sumac

#f77c0f
Notes

Hot Sumac (#F77C0F) 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 (28°, 94%, 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

Hot
adjective

Old English hāt, of high temperature — applied metaphorically to color since the eighteenth century for warm hues at high saturation. Hot pink, hot red: the implication is luminous intensity combined with thermal warmth. Sits in the bright-and-warm corner of the grid, alongside burning and vivid.

Sumac
noun

Rhus coriaria, the Mediterranean sumac whose dried red-orange berries are ground into the souring spice essential to Levantine za'atar and Persian fesenjān. The color refers to ground sumac in a brass spice tin: a saturated, slightly muted deep red-orange with the dusty finish of ground berry skin. Warmer than paprika, drier than rust.

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.
