How should I effectively use blue in UI design?

Here are some ways to use blue in your designs:

• Convey a sense of trust. The color blue is commonly associated with stability, confidence, and professionalism. Use it in designs for corporations, banks, and other firms you wish to present as reliable or reassuring.
• Promote a sense of calm. Use blue strategically in your designs to relax users. Tools like Zoom and Smartsheet utilize shades of blue to promote focus and productivity in work settings.
• Establish a visual hierarchy. Use different shades of blue to create a sense of visual hierarchy. Use lighter blue shades to call attention to more prominent items, such as buttons and headers.

Keep in mind that color and its meaning can change from culture to culture—and at any given time. If you are designing for a global audience, research color considerations for your specific regions.

Indigenous people in the United States continue to view it as a symbol of wisdom, spirituality, and healing.

Blue, as associated with the sky and ocean, evokes feelings of calmness and relaxation. These emotions help connect blue to additional feelings of trust and safety. Designers commonly use blue to help relieve stress, such as hospitals and offices.

What’s the history of blue?

The color blue derives its name from the Old French word “bleu,” which comes from the Proto-Indo-European language. The root “bhel” originally meant “to shine.” During prehistoric times, ancient civilizations created the pigment using minerals like lapis lazuli and azurite.

The ancient Egyptians heavily used the color blue, viewing it as a symbol of the divine. Ancient Egyptian civilization used blue so widely that they invented a hue we continue to reference as Egyptian blue; Egyptians synthesized the color from silica, lime, copper, and alkali. They utilized it in art, jewelry, cosmetics, and to paint the exterior of the pyramids. The ancient Greeks also valued the color blue, working it into art and architecture.

Through the Middle Ages and Renaissance periods, blue became associated with royalty. The pigment was rare and costly, making it more valuable than some precious metals, including gold. By the Industrial Revolution, chemists discovered how to make synthetic blue pigments, making the color more affordable.
