The hex color #0B21DB, a dark blue, presents significant accessibility challenges, especially for users with visual impairments. Its low lightness value of approximately 15% means that text rendered in this color requires very light text to achieve sufficient contrast. 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. Using white text (#FFFFFF) on a #0B21DB background achieves a high contrast ratio, generally exceeding these recommendations. However, avoid pairing this color with mid-tone or dark shades, as it will fail accessibility standards. Careful consideration is crucial when integrating #0B21DB into user interfaces or designs to ensure content is accessible to all users, including those with disabilities. Use contrast checking tools to evaluate the color combination.
