Sensible jobs for this swatch

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

Do not use #e3f1f6 as small body text on white — 1.16:1 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.
