Cerulean Blue

General Information

Cerulean Blue, represented by the hexadecimal code #1A4ECA, is a captivating shade of blue known for its resemblance to the clear, bright blue of the sky on a cerulean day. It is a vibrant and somewhat deep color, often associated with tranquility, serenity, and clarity. This color falls within the blue color spectrum, leaning towards a slightly more saturated and intense hue compared to lighter shades of blue like sky blue or baby blue. In color theory, Cerulean Blue is considered a cool color, capable of creating a sense of calm and stability. Its unique tone makes it a popular choice across various applications, from graphic design to fashion and interior decoration, due to its ability to capture attention while maintaining an overall feeling of peace and sophistication.

The hex color #1A4ECA, Cerulean Blue, presents specific accessibility considerations for web developers. Its contrast ratio against white (#FFFFFF) is approximately 2.3:1, which falls significantly short of the WCAG (Web Content Accessibility Guidelines) minimum requirement of 4.5:1 for normal text and 3:1 for large text. This means that using #1A4ECA for text on a white background can be difficult to read for users with visual impairments. To improve accessibility, developers should pair #1A4ECA with lighter background colors, such as light yellows, greens, or grays, or consider using it primarily for decorative elements rather than essential text. Adjusting the font weight can also help, using a bolder font increases legibility. Careful consideration of color pairings is crucial to ensure that content is accessible to all users, regardless of their visual abilities. Always test color combinations using accessibility tools to verify compliance with WCAG standards.
