The color #11168A, a deep shade of Ultramarine, presents several accessibility considerations for web design. Its low lightness value means it will have poor contrast with lighter text, potentially making content difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using this color for text requires careful pairing with very light backgrounds, and even then, it may not meet accessibility standards for all users. Consider using a lighter tint of this color or pairing it with a high-contrast color for improved accessibility. Additionally, avoid using this color as the sole means of conveying important information, as colorblind users may not be able to distinguish it effectively. Providing alternative cues, such as text labels or icons, ensures that all users can access the information.
