Serene Pluto Teal
Serene Pluto Teal (#0E7977) is a deep cyan 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 (179°, 79%, 26%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin serēnus, clear / unclouded. As a color modifier, serene implies a clear-and-untroubled quality where the hue carries the visual register of cloudless-bright-day atmospheric stability. Sits at the crisp-and-calm end of the grid, parallel to placid and untroubled in usage.
Latin Pluto, Roman-god-of-underworld-and-dwarf-planet. As a color modifier, pluto implies a Roman-god-of-underworld-and-Kuiper-belt-dwarf-planet quality, the visual register of Roman-Pluto-and-New-Horizons-flyby hand-Roman-god-of-underworld-and-Kuiper-belt-dwarf-planet Roman-Pluto-and-New-Horizons-flyby-and-Tombaugh-Regio pluto-and-Roman-god-of-underworld surfaces under Roman-Pluto-and-New-Horizons-flyby-and-Tombaugh-Regio 2015-flyby-and-heart-shaped-Tombaugh-Regio dwarf-planet-light. Sits at the modifier-and-zodiac end of the grid, parallel to neptune and saturn in usage.
Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
Closest matches

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.
