Manic Yew

#1bbe35
Notes

Manic Yew (#1BBE35) is a true green with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (130°, 75%, 43%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Manic
adjective

Greek manikós, raving / mad — sharing root with mania. As a color modifier, manic implies a saturated-and-overstimulated-and-extreme quality, the bright color of Andy-Warhol-and-Pop-Art late-Pop-Art repeated-and-multiplied portrait color schemes. Sits at the bright-and-active end of the grid, parallel to hyper and frenetic in usage.

Yew
noun

Taxus baccata, the European yew — a long-lived conifer (some specimens over 2,000 years old) traditionally planted in English churchyards. The color refers to mature yew foliage: a deep, slightly muted very dark green with the matte finish of resin-coated needle foliage. Darker than juniper.

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.
