Opulent Tropics
Opulent Tropics (#258445) is a deep 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 (140°, 56%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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 opulentus, rich / wealthy — derived from ops (wealth). As a color modifier, opulent implies a saturated-and-luxurious quality, the deep-rich color of Belle-Époque and Gilded-Age interior-decoration silk-and-velvet textiles. Sits at the bold-and-saturated end of the grid, parallel to lavish and sumptuous.
The Earth's equatorial belt between the Tropic of Cancer and the Tropic of Capricorn — the region of the world where the sun reaches direct overhead at some point of the year. Tropics refers to the unifying blue-green of tropical-zone ocean and lagoon water: a saturated, slightly cool deep blue-green.

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.
