Electric Opus Avocado
Electric Opus Avocado (#839F24) is a true yellow 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 (74°, 63%, 38%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.
Latin opus, work-or-composition. As a color modifier, opus implies a Latin-work-and-Magnum-Opus-and-Opus-Dei quality, the visual register of Magnum-Opus-and-musical-opus-number hand-Latin-work-and-Magnum-Opus-and-Opus-Dei Magnum-Opus-and-musical-opus-number-and-medieval-cathedral-opus opus-and-Latin-work surfaces under Magnum-Opus-and-musical-opus-number-and-medieval-cathedral-opus monastic-scriptorium-and-medieval-cathedral-fabric craft-and-composition-light. Sits at the modifier-and-Latin end of the grid, parallel to magnus and ergo in usage.
Persea americana, the buttery drupe domesticated in Mesoamerica seven thousand years ago and named for the Aztec āhuacatl. The color refers to ripe avocado flesh just under the dark skin: a soft, slightly muted yellow-green with the warm undertones of plant fat. Earthier than pistachio, lighter than olive, with the recent kitchen association of a fruit only recently turned global staple.

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.
