Aflame Bottle

#25bb60
Notes

Aflame Bottle (#25BB60) 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 (144°, 67%, 44%) 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

Aflame
adjective

Old English on-flamme, on-fire. As a color modifier, aflame implies a saturated-and-burning-bright quality, the bright color of autumn-Maple-and-Oak peak-color deciduous-foliage and Bonfire-Night large-flame fire emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.

Bottle
noun

The traditional dark green of European wine and beer bottles — produced by adding iron oxide to the glass batch to filter UV that would damage the contents. The color refers to a Riesling or Burgundy bottle held against the light: a deep, slightly blue-shifted green with the optical translucency of glass. Darker than spruce, cooler than forest, with the cellar weight of a color that's been protecting wine since the seventeenth century.
