#3f74a3 - Decoration Blue color

A cool, medium-dark steel blue with muted denim tones and a subtle gray cast.

The color balances approachability with seriousness, making it suitable for corporate identities, user interfaces, and sophisticated home accents. Pair it with warm neutrals or soft creams for contrast, or with pale blues and silvery greys for a monochromatic, modern palette.
