#3f6c8f - Rainy Lake color

This shade is a cool, muted steel-blue with subtle teal undertones—think a storm-tossed sea at dusk or well-worn indigo denim softened by gray. It reads sophisticated and restrained, conveying calm, reliability, and a slightly nautical character. It pairs beautifully with crisp white for contrast, warm terracotta or burnt orange for energetic accents, and soft beige or warm gray for cozy, modern interiors. Use it for professional brand identities, user interfaces, and textiles where a stable, refined blue is desired.
