The hex color #214DB6, also known as Cerulean Blue, presents several accessibility considerations for web developers. Its relatively low luminance value means that it requires careful pairing with text and background colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Therefore, when using #214DB6 as a background color, it's crucial to select a light-colored text to meet these contrast requirements. Furthermore, avoid using this color as the sole indicator of interactive elements, as users with color vision deficiencies may not be able to differentiate them. Providing additional visual cues, such as underlines or icons, enhances usability for all users. Proper implementation of ARIA attributes can further improve accessibility for assistive technologies.
