Dynamic Sansho
Dynamic Sansho (#9CF08B) is a soft green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (110°, 77%, 74%) places it in the highly saturated band at a light 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
From the Greek dynamis, power — used as a color modifier since the late nineteenth century for hues that read as energetic and active. Dynamic red, dynamic orange: the implication is saturation combined with optical motion. Sits at the bright-bucket center alongside vibrant and lively.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
