Iridescent Lux Malachite
Iridescent Lux Malachite (#5DE7A8) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (153°, 74%, 64%) 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
Latin Īris, rainbow — adjectival suffix -escent, named for the Greek goddess of the rainbow. As a color modifier, iridescent implies a saturated-and-multi-spectrum-shifting quality, the bright color of peacock-feather-and-soap-bubble structurally-colored-and-thin-film optical-interference patterns. Sits at the bright-and-shifting end of the grid, parallel to prismatic and holographic in usage.
Latin lux, light. As a color modifier, lux implies a Latin-light-and-Fiat-Lux-and-Lux-Aeterna quality, the visual register of Genesis-Fiat-Lux-and-Lux-Aeterna hand-Latin-light-and-Fiat-Lux-and-Lux-Aeterna Genesis-Fiat-Lux-and-Lux-Aeterna-and-Requiem-mass lux-and-Latin-light-and-Fiat-Lux surfaces under Genesis-Fiat-Lux-and-Lux-Aeterna-and-Requiem-mass Vulgate-and-Tridentine-Mass primal-light. Sits at the modifier-and-Latin end of the grid, parallel to ignis and opus in usage.
A copper carbonate mineral — Cu₂CO₃(OH)₂ — that crystallizes as concentric green bands in oxidized copper deposits. Mined for ornamental stone since ancient Egypt, ground into pigment for medieval European painting, polished into the malachite columns of the Russian Hermitage. The color refers to a polished cabochon: a saturated, slightly muted green with the high shine of stone and the visible banding of growth rings.

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.
