The hex color #1C51CA, a shade of Cerulean Blue, presents several accessibility considerations for web developers. Its relatively low luminance requires careful pairing with text and other UI elements to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. When using #1C51CA as a background, consider using white (#FFFFFF) or very light shades of gray as the text color to meet these contrast requirements. Similarly, if using #1C51CA for text, a very light or white background would be necessary. Tools like WebAIM's contrast checker can be valuable in verifying compliance. Additionally, providing alternative visual cues, such as underlines or icons, alongside color coding can further enhance accessibility for users with color vision deficiencies.
