Plumbed Cognac

#301a02
Notes

Plumbed Cognac (#301A02) 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 (31°, 92%, 10%) 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 azure. 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.

Cognac
noun

The eastward-of-Bordeaux French region — and the brandy distilled there from Ugni Blanc grapes and aged in Limousin oak. The color refers to a 30-year-old XO Cognac in a snifter: a saturated, slightly red-shifted deep gold-brown with the optical complexity of long oak aging. Warmer than brandy, deeper than whiskey.
