Clean Easter Turquoise

#11b7ca
Notes

Clean Easter Turquoise (#11B7CA) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (186°, 84%, 43%) places it in the highly saturated band at a mid 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clean
adjective

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Easter
modifier

Old English Ēastre, Easter. As a color modifier, easter implies a Paschal-and-spring-feast quality, the visual register of Roman-Catholic-and-Anglican Easter-feast spring-resurrection white-and-gold-and-cream paschal liturgical surfaces under Paschal-feast spring-resurrection candlelight. Sits at the modifier-and-time end of the grid, parallel to advent and yule in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.
