Plumbed Chrome

#661906
Notes

Plumbed Chrome (#661906) is a deep red 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 (12°, 89%, 21%) 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.

Chrome
noun

Lead chromate (PbCrO₄) — the chrome orange pigment introduced in 1809, brilliant but heavily toxic and reactive. Largely replaced by cadmium pigments in the twentieth century. The color refers to a freshly mixed chrome-orange in a Victorian color-merchant's stock: a saturated, slightly red orange with the matte finish of lead-based pigment. Brighter than ochre.

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.
