The color #1E11A3, a deep ultramarine, presents some accessibility challenges, particularly in text-based applications. Its low luminance value requires careful consideration of contrast ratios. When used as a foreground color, it's crucial to pair it with a light background to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, and 3:1 for large text, as per WCAG guidelines. Tools like contrast checkers can help evaluate the suitability of color combinations. In interactive elements such as buttons or links, sufficient contrast is vital to ensure users can easily identify interactive components. Moreover, avoid using color as the sole indicator of functionality, as it may exclude users with color vision deficiencies. Providing alternative visual cues, such as underlines or icons, is advisable to enhance usability for all users. This ensures a more inclusive and accessible design.
