General Information about Cerulean Blue

Cerulean Blue, represented by the hex code #264AB0, is a medium-dark shade of blue that falls within the blue color family. It is often associated with feelings of calmness, stability, and trust. In the RGB color model, it is composed of 15.3% red, 29% green, and 69% blue. The name 'Cerulean' comes from the Latin word 'caeruleus,' which means 'dark blue' or 'sky blue.' Historically, cerulean was associated with the pigment derived from cerussite, a mineral containing lead carbonate. Today, it is widely used in various fields, including art, design, and web development, to evoke a sense of serenity and professionalism. Its unique tone makes it versatile for both background and accent colors, but it's important to consider its contrast with other colors for accessibility.

The hex color #264AB0, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of 16 means that it may not provide sufficient contrast when used as text against a white background or as a background for white text. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #264AB0, it is important to pair it with lighter colors to ensure readability and accessibility for all users. Tools like contrast checkers can help determine if the color combination meets accessibility standards. Consider using it for larger graphical elements, where the contrast requirements are less stringent, or pair it with very light shades to achieve the right contrast ratio.
