Heavy Amazonite
Heavy Amazonite (#25823F) is a deep 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 (137°, 56%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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
Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.
A blue-green variety of microcline feldspar — colored by trace lead and water in its crystal structure. Mined since ancient times in the Russian Urals and now in Colorado, Madagascar, and Brazil. The color refers to a polished amazonite cabochon: a soft, slightly muted blue-green with the cloudy translucency of feldspar. Cooler than jade, warmer than cerulean, with the mineral-trade specificity of a stone named for the Amazon basin where it doesn't actually occur.
