The hex color #1B4DBB, a shade of Cerulean Blue, presents some accessibility challenges in web design. Its relatively low luminance can lead to insufficient contrast when paired with lighter text or background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1B4DBB, it's crucial to test the color contrast against its paired elements to ensure readability for users with visual impairments. Tools like WebAIM's Contrast Checker can be invaluable in this process. Consider using lighter shades of yellow or white for text on a #1B4DBB background, or darker shades for backgrounds with #1B4DBB text. Also, provide alternative visual cues for interactive elements, such as underlines or icons, to further improve accessibility.
