Quiet Indaco
Quiet Indaco (#9EB8FB) is a soft azure with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (223°, 92%, 80%) places it in the highly saturated band at a light 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 amber. 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.
The Italian word for indigo — borrowed via Greek indikon (Indian thing). Indaco in Italian art vocabulary refers specifically to the deep-blue plant-dye pigment used in Italian Renaissance painting for the Marian mantles and aristocratic dress. The color refers to indaco pigment in tempera: a saturated, slightly cool deep blue. The Italian cousin of indigo.

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.
