Quiet Ammolite

#adf3db
Notes

Quiet Ammolite (#ADF3DB) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (159°, 74%, 82%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Quiet
adjective

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.

Ammolite
noun

The fossilized iridescent shell of Placenticeras ammonites — mined principally from the Bearpaw Formation in southern Alberta, Canada. The color refers to a polished ammolite cabochon: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored ancient nacre.
