Steeped Mauritius
Steeped Mauritius (#053116) is a deep 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 (143°, 81%, 11%) places it in the highly saturated band at a dark 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English stēpan, to dip / soak — past-participle of steep. As a color modifier, steeped implies the deep-and-saturation-rich quality of dye-bath-saturated textile, where the hue has reached fiber-saturation. Sits at the deep-and-saturated end of the grid, parallel to infused and suffused.
The Indian Ocean island east of Madagascar — and the saturated turquoise of Mauritian lagoon water at Le Morne and Tamarin Bay. Mauritius color refers to a Mauritian lagoon at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm Indian Ocean water.

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 sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
