Sensible jobs for this swatch
Do not use #b4ddff as small body text on white — 1.43:1 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: Openness, clarity, and communication. Soft and approachable for modern interfaces. Common uses still include buttons, charts, and accents in the Light Blue range — always verify the pair for this exact hex in the contrast checker.
