Flaming Esmeralda
Flaming Esmeralda (#02B21C) is a true green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (129°, 98%, 35%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
Old French flamme, flame — present-participle of flame. As a color modifier, flaming implies a saturated-and-fire-and-bright-color quality, the bright color of autumn-Maple-and-Oak deciduous-foliage fall-color and Yule-log fire emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.
The Spanish word for emerald — used for the Esmeralda of Colombian deposits (the world's largest source) and the Esmeraldas province of Ecuador. The color refers to a Muzo-mine Colombian emerald: a saturated, slightly cool deep green with the gem's signature internal life. The Spanish cousin of emerald.

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.
