Lambent Kiln Peridot
Lambent Kiln Peridot (#87D88E) 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 (125°, 51%, 69%) 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
Latin lambēns, licking-lightly — present-participle of lambere (to lick). As a color modifier, lambent implies a saturated-and-soft-flickering quality, the bright color of candle-flame-and-firefly gentle-flickering light-emission against the surrounding darkness. Sits at the bright-and-soft end of the grid, parallel to glimmering and flickering in usage.
Old English cyln, brick-or-pot-firing oven. As a color modifier, kiln implies a fired-and-glazed quality, the visual register of Stoke-on-Trent-and-Jingdezhen hand-fired pottery-and-brickwork high-temperature ceramic-firing surfaces under industrial-pottery-firing Stoke-and-Jingdezhen kiln-yard light. Sits at the modifier-and-place end of the grid, parallel to mill and forge in usage.
The transparent green variety of olivine — the gem mined from Egyptian Zabargad Island since pharaonic times and now from arid mountain ranges in Pakistan, Arizona, and Vietnam. The color refers to a faceted peridot: a clean, slightly yellow-shifted green with the gem's signature internal warmth. Lighter than emerald, brighter than olivine in its rough state, with the unusual gem-trade quality of being one of the few minerals that occurs in only one color.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
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.
