Stalwart Plot Emerald
Stalwart Plot Emerald (#2EA452) 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 (138°, 56%, 41%) 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 stǣl-wyrðe, stable-and-worthy. As a color modifier, stalwart implies a saturated-and-loyal-and-firm quality where the hue carries the dependable-and-trustworthy visual presence of a Knight-Templar guard. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.
Old English plot, small-piece-of-ground. As a color modifier, plot implies a tilled-garden-bed quality, the visual register of English-cottage-garden-and-allotment hand-tilled-and-cultivated small market-garden vegetable-bed surfaces under English-cottage-garden-and-allotment summer-tilling light. Sits at the modifier-and-place end of the grid, parallel to yard and garden in usage.
A chromium-tinged variety of beryl — the gemstone mined from the Cleopatra-era Mons Smaragdus in Egypt, the Muzo deposits of Colombia, and the Sandawana mines of Zimbabwe. Emerald green refers to a high-clarity faceted emerald with strong color saturation: a saturated, slightly blue-shifted green with the gem's signature internal life. Cooler than fern, warmer than teal, with the heraldic weight of two thousand years of royal favor.

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.
