#8EB8CE Hex Color

Moon Jellyfish is an excellent choice for UI backgrounds because its muted, unsaturated nature provides a calm backdrop that maintains strong contrast with standard dark text. This ensures your interface remains accessible while avoiding the visual intensity of a pure, saturated blue.

This ashy blue pairs beautifully with deep charcoal or soft slate grays to maintain a monochromatic, professional feel. For a more balanced, warm contrast, introduce muted terracotta or soft earth tones to ground the otherwise cool, airy character of the palette.
