Forthright Sansho

#177505
Notes

Forthright Sansho (#177505) is a deep green 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 (110°, 92%, 24%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Sansho
noun

Zanthoxylum piperitum, the Japanese sansho pepper — related to Sichuan peppercorn, with citrus-tinted numbing flavor used in unagi glazes and the spice mix shichimi tōgarashi. The color refers to fresh-ground sansho powder in a small ceramic bowl: a saturated, slightly cool yellow-green with the matte finish of dried citrus-family seed.

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.
