Spare Piombo

#28050f
Notes

Spare Piombo (#28050F) 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 (343°, 78%, 9%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spare
adjective

Old English spær, frugal, scant — used as a color modifier since the seventeenth century for hues that read as minimal and unornamented. Spare gray, spare white: very low saturation combined with optical restraint. Sits at the neutral-bucket alongside bare and plain.

Piombo
noun

Italian piombo, lead — adopted into Italian color terminology for the deep-lead-gray of Renaissance lead-glass leaded-light cathedrals and piombatura lead-roof flashing. Piombo color refers to a Florentine-cathedral piombatura lead-roof flashing in raking light: a dark cool-gray with the matte finish of lead-and-tin foundry residue on hand-cast Tuscan lead-flashing.
