Sinewy Kohlrabi

#409e1b
Notes

Sinewy Kohlrabi (#409E1B) is a true 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 (103°, 71%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Sinewy
adjective

Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged in usage.

Kohlrabi
noun

Brassica oleracea var. gongylodes — the swollen-stem cabbage variety used in German and Indian cooking. Kohlrabi color refers to a fresh raw kohlrabi bulb after its leaves are removed: a soft, slightly cool pale green with the matte finish of cruciferous root-stem.

Display P3 representation

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 is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
