The hex color #0D3D8A, also known as Congress Blue, presents some accessibility challenges, especially regarding color contrast. When used as a foreground color for text, it requires careful consideration of the background color. To ensure readability and compliance with accessibility standards like WCAG (Web Content Accessibility Guidelines), it's crucial to use a light background color to achieve a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools are available to check color contrast ratios and help in selecting appropriate color combinations. Using this dark blue with equally dark shades will cause readability issues. Designers should ensure sufficient contrast for users with visual impairments. Consideration should also be given to those with cognitive disabilities. Therefore, using this color should be carefully planned.
