#404e61 - Admiralty color

This deep slate-blue gray reads as a cool, muted navy with subtle teal undertones. It evokes a stormy seascape at dusk—calm, reserved, and slightly industrial—making it well suited for sophisticated interfaces, professional branding, or moody interiors. It pairs nicely with warm metallics like copper or brass, mustard accents, and crisp off-whites for contrast. Use it as a background or accent to lend solidity, composure, and understated elegance without overwhelming brighter colors.
