Quiet Parsec Kingfisher
Quiet Parsec Kingfisher (#1893A7) is a true 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 (188°, 75%, 37%) 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
Latin quietus, at rest — used as a color modifier since the medieval period for hues that read as restrained. Quiet pink, quiet blue: low saturation combined with optical calmness. Sits across the crisp and hushed buckets where the color is present but doesn't ask for attention.
Coined 1913, parallax-second. As a color modifier, parsec implies a deep-space-and-stellar-distance quality, the visual register of 3.26-light-year-parsec hand-deep-space-and-stellar-distance 3.26-light-year-and-Hipparcos-and-Gaia-parsec parsec-and-deep-space-and-stellar-distance surfaces under 3.26-light-year-and-Hipparcos-and-Gaia-parsec galactic-cartography-and-stellar-cradle stellar-distance-light. Sits at the modifier-and-cosmic end of the grid, parallel to orbit and nebula 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.

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.
