Aflame Aquamarine

#31b864
Notes

Aflame Aquamarine (#31B864) 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 (143°, 58%, 46%) 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.

Aquamarine
noun

An iron-tinged variety of beryl — the gemstone mined from pegmatite veins in Brazil, Madagascar, and the Pakistani Karakoram. Named for the Latin aqua marina, seawater. The color refers to a faceted Santa Maria aquamarine: a clean, slightly green-shifted blue with the gem's high refractive brilliance. Lighter than sapphire, deeper than seafoam, with the gem-trade specificity of a stone graded primarily for color depth.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
