The color #0D1F8B, a deep shade of blue, presents accessibility challenges primarily due to its low luminance. When used as text, it requires a light background to ensure sufficient contrast for readability, adhering to WCAG guidelines for color contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. For users with visual impairments, especially those with low vision, insufficient contrast can render text illegible.

Avoid pairing this color with dark shades like black or gray, as this would exacerbate accessibility issues. Testing color combinations with accessibility tools and gathering user feedback can help identify and rectify potential accessibility problems.
