Reticent Tar

#1c0003
Notes

Reticent Tar (#1C0003) 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 (354°, 100%, 5%) 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

Reticent
adjective

Latin reticēns, silent — present-participle of reticēre. As a color modifier, reticent implies a neutral-and-quietly-withholding quality where the hue carries the visual register of Quaker-and-Puritan quietly-withholding-and-restrained color-decision. Sits at the neutral-and-quiet end of the grid, parallel to taciturn and laconic in usage.

Tar
noun

The viscous black liquid produced by distilling pine wood, coal, or peat — used since antiquity for waterproofing ship hulls, weatherproofing roofs, and treating skin conditions. The color refers to fresh pine tar: a deep, slightly muted black with the glossy finish of a viscous oil. Warmer than pitch, deeper than soot, with the maritime weight of a substance whose smell defined every harbor before petroleum.
