Unblemished Bistre

#874906
Notes

Unblemished Bistre (#874906) 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°, 91%, 28%) 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

Unblemished
adjective

Old French blesmir, to wound — negative-prefix un- plus past-participle of blemish. As a color modifier, unblemished implies a clear-and-flawless quality where the hue carries no defect or imperfection. Sits at the crisp-and-clean end of the grid, parallel to pristine and spotless in usage.

Bistre
noun

A traditional French painter's pigment made from soot suspended in gum arabic — used for sepia-style washes in Old Master drawings. The color refers to a bistre wash on Rembrandt-period drawing paper: a soft, slightly muted warm brown with the translucent finish of soot-and-binder. Cooler than walnut, drier than caramel.

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.
