Stripped Mute Kingfisher
Stripped Mute Kingfisher (#40A5BA) is a true cyan 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 (190°, 49%, 49%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English stripian, to strip — past-participle of strip. As a color modifier, stripped implies a clear-and-bared-and-unornamented quality, the crisp color of Cistercian-and-Bauhaus anti-ornamental stripped-down architectural interior. Sits at the crisp-and-stripped end of the grid, parallel to spare and bare in usage.
Latin mutus, silent-or-dumb. As a color modifier, mute implies a hushed-and-tongue-stilled-and-quieted quality, the visual register of silent-film-and-monastic-mute tongue-stilled-and-cloister-quieted silent-film-and-monastic-and-cloister tongue-stilled-and-still-and-quiet surfaces under silent-film-and-monastic vigil-and-cloister hush-and-quiet vow-of-silence light. Sits at the modifier-and-mood end of the grid, parallel to hush and still in usage.
The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.

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.
