#518FD1 Hex Color

Blue Dart #518fd1 pairs well with navy for depth, warm gray for a restrained professional look, and white for clean contrast; a small terracotta accent can add warmth without overpowering the blue.

Blue Dart #518fd1 provides about a 6.2:1 contrast ratio with black text, meeting WCAG AA for normal body text; white text has weaker contrast, so dark text is the safer choice for paragraphs and other small type.

Blue Dart #518fd1 works well for technology, finance, healthcare, and government interfaces because its cool, moderately muted blue feels dependable without becoming too dark; use it for panels, accents, and supporting brand elements beside navy or warm gray.
