Plumbed Sumac

#752806
Notes

Plumbed Sumac (#752806) is a deep orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (18°, 90%, 24%) places it in the highly saturated band at a dark 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plumbed
adjective

Latin plumbum, lead — past-participle of plumb (to measure depth with a lead-weighted line). As a color modifier, plumbed implies a deep-and-cool quality measured-to-its-fullest-depth, the dark cool-gray of lead-and-pewter metallic surfaces. Sits at the deep-and-cool end of the grid, parallel to fathomless with metallic register.

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.
