Incandescent Kohlrabi

#39b017
Notes

Incandescent Kohlrabi (#39B017) is a true 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 (107°, 77%, 39%) places it in the highly saturated band at a mid 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

Incandescent
adjective

Latin incandēscēns, growing-hot — present-participle of incandēscere, sharing root with candere (to shine). As a color modifier, incandescent implies a saturated-and-glowing-hot quality, the bright color of tungsten-filament-glow incandescent-lamp light. Sits at the bright-and-warm end of the grid, parallel to glowing and blazing 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.

Wide gamut

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.
