Cerulean

Cerulean (#1DACD6) is a vivid medium sky blue from the Crayola palette, named after the Latin word for sky. It captures the bright, open quality of a clear summer sky or tropical lagoon, with more saturation than the X11 cerulean variants. As the celebrated color of the new millennium announced by Pantone in 1999, it carries cultural resonance as the defining blue of the 2000s.

True cyan sits at the boundary of blue and green in the visible spectrum, projecting futurism, precision, and digital innovation. It is a primary color in CMYK printing and RGB displays, giving it a distinctly technological identity. Cyan suggests cutting-edge thinking and clear communication.

Medium cyan is a staple in tech branding, cloud computing services, and developer tools. It works well for interactive elements, link hover states, and data visualization highlights. Because cyan is highly saturated, use it as an accent rather than a dominant color to avoid visual strain.
