The color #100791, a deep ultramarine, presents several accessibility considerations for web development. Due to its dark nature, sufficient contrast is crucial when pairing it with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability for users with visual impairments. White or very light shades of yellow, green, or cyan are excellent choices for text color when using #100791 as a background. Avoid using it with dark text colors, as the low contrast can make content illegible. Also, consider providing alternative visual cues, such as underlines or icons, for links and interactive elements to ensure they are easily identifiable for all users, including those with color vision deficiencies. Careful attention to contrast and supplementary visual cues will enhance the accessibility of designs incorporating this rich blue hue.
