#A4DDE9 Hex Color

Use Luminescent Blue as a soft background layer for modern interfaces that need an airy, breathable feel. Because it sits high on the lightness scale, it requires dark text like charcoal to maintain proper accessibility and readable contrast levels.

Avoid placing #a4dde9 directly against pure white, as the lack of contrast makes the blue appear washed out and indistinct. Instead, pair it with muted neutrals or deeper tones to preserve the refreshing, icy character of the hue.
