#2B5DBB

General Information

Cerulean Blue, represented by the hexadecimal color code #2B5DBB, is a captivating shade of blue often associated with serenity, depth, and the vastness of the ocean. It is located in the blue region of the color spectrum, exhibiting a blend of cyan and azure tones. In color theory, Cerulean Blue conveys a sense of calmness, trust, and stability. Its rich hue makes it a popular choice across various design disciplines, including web design, graphic arts, and fashion. The color's unique characteristics stem from its specific combination of red, green, and blue (RGB) values, which define its precise appearance and distinguish it from other shades of blue.

The hex color #2B5DBB, also known as Cerulean Blue, presents specific accessibility considerations, especially for web content. Its contrast ratio against white (#FFFFFF) is relatively low, which can pose challenges for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for text and interactive elements to be easily perceivable. Using #2B5DBB for text on a white background may not meet the minimum contrast ratio thresholds, potentially making it difficult for some users to read. To improve accessibility, consider pairing #2B5DBB with lighter shades or using it sparingly for decorative elements. Testing with accessibility tools and getting feedback from users with disabilities are crucial steps to ensure inclusive design practices when using this color.
