Aglow Conure

#40b837
Notes

Aglow Conure (#40B837) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (116°, 54%, 47%) 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

Aglow
adjective

Old English on-glōwan, on-glow — sharing root with glow and gleam. As a color modifier, aglow implies a saturated-and-lit-from-within quality, the bright color of fireplace-and-jack-o-lantern interior-glow-lit warm-light emission against ambient darkness. Sits at the bright-and-warm end of the grid, parallel to glowing and aflame in usage.

Conure
noun

The genus Pyrrhura and related green parrots of the South American mainland — popular pet birds with predominantly green plumage. Conure color refers to the green back of a green-cheeked conure (P. molinae): a saturated, slightly cool deep green with the matte finish of carotenoid-and-structural feather color.

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.
