Genuine Fennel
Genuine Fennel (#E3FDD5) is a soft lime with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (99°, 91%, 91%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin genuinus, natural, innate — used as a color modifier since the sixteenth century for hues that read as authentic rather than imitated. Genuine indigo, genuine ochre: moderate-to-high saturation combined with the optical impression of a hue from real pigment rather than synthetic dye. Sits at the crisp-bucket alongside true and honest.
Foeniculum vulgare, the Mediterranean herb whose feathery yellow-green fronds and bulb-like stem base are essential to Italian and French cooking. The color refers to fresh fennel fronds: a saturated, slightly cool feathery yellow-green with the matte finish of dissected leaves. Drier than dill.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
