Rousing Sumac

#e98818
Notes

Rousing Sumac (#E98818) 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 (32°, 83%, 50%) 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

Rousing
adjective

Old English rūsan, to rush — present-participle of rouse. As a color modifier, rousing implies a saturated-and-wakening-and-active quality, the bright color of dawn-chorus-and-morning-bell atmospheric-and-aural stimulation. Sits at the bright-and-active end of the grid, parallel to awakening and invigorating in usage.

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.
