Alight Chili Seafoam
Alight Chili Seafoam (#26C165) 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%, 45%) 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
Old English ā-lihtan, to set alight — past-participle of alight. As a color modifier, alight implies a saturated-and-currently-illuminated quality, the bright color of Christmas-tree and Diwali-lamp festival-decoration illuminated-and-twinkling emission. Sits at the bright-and-warm end of the grid, parallel to aflame and aglow in usage.
Nahuatl chīlli, capsicum-fruit. As a color modifier, chili implies a Mesoamerican-capsicum-and-fiery quality, the visual register of Mesoamerican-and-Oaxacan-chili hand-Mesoamerican-capsicum-and-fiery Mesoamerican-and-Oaxacan-chili-and-Yucatec-and-Veracruzano chili-and-Mesoamerican-capsicum surfaces under Mesoamerican-and-Oaxacan-chili-and-Yucatec-and-Veracruzano Oaxaca-and-Veracruz-and-Yucatán Mesoamerican-spice-light. Sits at the modifier-and-flavor end of the grid, parallel to pepper and pimento in usage.
The pale, slightly translucent green-blue of foam on a breaking wave — light scattered through micron-scale air bubbles in salt water, with a touch of the sea's color showing through. Seafoam green refers specifically to that desaturated tint: a soft, very pale green-blue with the optical lightness of small bubbles in motion. Lighter than mint, cooler than celadon.

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.
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.
