Cavalier Fiddlehead

#279f20
Notes

Cavalier Fiddlehead (#279F20) 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 (117°, 66%, 37%) 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

Cavalier
adjective

Italian cavaliere, horseman / knight via Latin caballārius. As a color modifier, cavalier implies a saturated-and-chivalrous-and-aristocratic quality, the deep-rich color of English-Civil-War royalist Cavalier military-faction velvet-and-lace-and-feathered-hat livery. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Fiddlehead
noun

The tightly coiled emerging frond of any fern — particularly the edible fiddleheads of Matteuccia struthiopteris (ostrich fern), eaten as a foraged spring delicacy in New England. Fiddlehead color refers to a fresh-emerged fern fiddlehead: a saturated, slightly cool yellow-green with the satin finish of curled new growth.

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.
