Sensible jobs for this swatch

page or card backgrounds
text or icons on charcoal / dark mode

Do not use #cddef8 as small body text on white — 1.36:1 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: Trust, calm, and professionalism. The most used color in SaaS, finance, and healthcare. Common uses still include buttons, charts, and accents in the Blue range — always verify the pair for this exact hex in the contrast checker.
