Sociable Cirrostratus
Sociable Cirrostratus (#566863) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (163°, 9%, 37%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin sociābilis, companionable — adjectival suffix -able. As a color modifier, sociable implies a neutral-and-friendly-and-welcoming quality where the hue carries the visual register of Edwardian-and-American-Country friendly-and-welcoming-hosting interior-decoration-and-textile coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to affable and amiable in usage.
Latin cirrus (curl) and stratus (layer) — the cool-pale-gray high-altitude cirrostratus veil-cloud, the iconic halo-producing cloud-deck preceding warm-front weather. Cirrostratus color refers to a cirrostratus-veiled mid-October sky over the Atlantic-coast of England: a balanced cool gray with the optical complexity of high-altitude ice-crystal scattering and the 22°-halo refraction-rainbow.

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.
