Cerulean (#007BA7) is a captivating sky-blue hue that embodies tranquility and clarity. Named from the Latin "caeruleus" meaning "dark blue" or "blue-green," this distinctive color sits perfectly between azure and steel blue on the color spectrum.

This serene shade evokes clear summer skies and peaceful ocean depths, making it psychologically calming and stress-reducing. Pantone famously declared cerulean the "color of the millennium" in 1999, highlighting its universal appeal and timeless nature. The United Nations even chose cerulean for their emblem as "the opposite of red, the color of war."

In design applications, cerulean creates fresh, airy spaces perfect for promoting mental clarity and relaxation. It pairs beautifully with warm complements like coral and peach for vibrant contrast, or with white and silver for sophisticated, crisp aesthetics. For depth, combine it with navy blue or charcoal.

Historically significant in art, cerulean was beloved by Impressionists like Claude Monet and Van Gogh, who used it to capture atmospheric effects and natural light. Today, it remains popular in interior design, branding, and digital interfaces where trust, dependability, and calm professionalism are desired.

Whether creating peaceful living spaces, trustworthy brand identities, or refreshing digital experiences, cerulean offers versatile elegance that never goes out of style.
