Clear Spa

#acf4b8
Notes

Clear Spa (#ACF4B8) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (130°, 77%, 82%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Spa
noun

A mineral-spring resort — named for the Belgian town of Spa whose iron-rich springs have drawn visitors since the sixteenth century. Spa color refers to a thermal spring pool at Saturnia in Tuscany: a saturated, slightly cool deep blue-green with the optical complexity of mineral-saturated water.
