The color #1E4EC8, also known as Cerulean Blue, presents several accessibility considerations for web development. Its relatively low luminance can pose challenges for users with visual impairments, particularly when used as text against a white or light-colored background. To ensure readability, it's crucial to maintain a sufficient contrast ratio, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using online contrast checkers can help verify compliance. Furthermore, consider providing alternative text descriptions for images or graphics that incorporate this color to make content accessible to screen reader users. Employing colorblindness simulators during the design process can also help identify potential issues for users with color vision deficiencies and guide adjustments to improve overall accessibility. Finally, avoid using color as the sole means of conveying information; supplement it with text or other visual cues.
