Sensible jobs for this swatch

supporting UI accents
text or icons on charcoal / dark mode

Do not use #55aaaf as small body text on white — 2.71:1 misses WCAG AA (4.5:1). Pair it with a darker shade from the scale below, or check pairs in the contrast checker.

Family context: Freshness, clarity, and innovation. Great for tech accents and clean digital products. Common uses still include buttons, charts, and accents in the Cyan range — always verify the pair for this exact hex in the contrast checker.
