Princely Sumac

#c64703
Notes

Princely Sumac (#C64703) is a true orange with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (21°, 97%, 39%) 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

Princely
adjective

Latin prīnceps, first / chief — adjectival suffix -ly. As a color modifier, princely implies a saturated-and-royal-secondary quality, the deep-rich color of European crown-prince coronet-and-livery vestment. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and regal 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.
