#221188 Hex Color

Because this shade is quite dark, white text creates a 14:1 contrast ratio against it, which exceeds accessibility standards. It serves as an excellent, high-readability background choice for interfaces that require both elegance and strict compliance with WCAG guidelines.

This deep indigo pairs naturally with crisp white or light gray for high-contrast UI, but also works well with metallic accents like gold or silver. For softer palettes, it complements muted lavender or dusty pink tones by balancing its intense, cool energy.
