Misty blue (#B5C7EB) is a gentle, muted shade that captures the essence of a serene morning sky or tranquil mist. With its soft blend of blue and subtle gray undertones, this color evokes feelings of calmness, peace, and trustworthiness—making it perfect for creating soothing digital experiences.

In UI design, misty blue excels as a background color that reduces eye strain while maintaining visual appeal. It works beautifully for secondary buttons and less critical interface elements, providing presence without overwhelming primary actions. The color's psychological association with trust makes it particularly valuable for healthcare, wellness, and productivity applications.

Misty blue pairs harmoniously with other soft tones like powder blue, periwinkle, and slate blue for monochromatic schemes. For contrast, consider warm neutrals like champagne or cream. The color also complements dusty rose for a romantic palette or mint green for a fresh, natural feel.

Whether you're designing meditation apps, corporate interfaces, or calming brand identities, misty blue offers the perfect balance of sophistication and serenity.
