Cerulean Blue, with its hex code #2257C4, presents specific accessibility considerations for web design. When used as a background color, ensure that the foreground text provides sufficient contrast to meet WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Lighter text colors like white or very light grays are generally needed to achieve adequate contrast. If used for interactive elements such as buttons or links, hover and focus states must also be designed with accessibility in mind, providing clear visual cues for users with visual impairments. Additionally, avoid using color as the sole means of conveying information; supplement it with text or icons to accommodate users with color blindness. Thorough testing with accessibility tools is crucial to ensure compliance and optimal user experience.
