#4466ee - The Rainbow Fish color

This shade is a vivid, saturated royal blue with cool, slightly violet-leaning undertones. It reads as bright and energetic while remaining crisp and modern—an electric cobalt that pops on screen without feeling neon. It conveys trustworthiness and tech-forward confidence, working well for call-to-action buttons, branding accents, and interfaces. Pairs beautifully with warm oranges or golds for high contrast, or with soft grays and whites for a clean, contemporary palette.
