Solid Dark Blue

Blue exterior walls often harmonize with natural elements like the sky and sea. For example, the light blue mirrored glass facade of Boston's Hancock Building reflects its surroundings, creating a 'sky and building merge' visual effect that enhances the building's modernity and spatial extension. This design approach is particularly suitable for coastal cities or eco-themed buildings, creating a fresh and natural atmosphere.

A sense of calm: Psychological studies show that blue can reduce anxiety, making it ideal for offices and hospitals where a tranquil environment is needed.

Professional feel: Darker blues, such as slate blue, are commonly used in industrial buildings. They help alleviate monotony while conveying a sense of rationality and technology.

Dynamic lighting effects: Light blue exterior tiles or paint exhibit gradient effects under different lighting conditions, from the soft sky blue at dawn to the deep lake blue at dusk, adding dynamic beauty to the architecture.
