The hex color #0B3E90, also known as Congress Blue, presents certain accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. It is crucial to avoid pairing this dark blue with mid-tone colors, as the contrast would likely be insufficient for users with visual impairments. Careful consideration should be given to the text size, font weight, and color combinations to ensure that the content is accessible to a wide range of users, including those with low vision or color blindness. Tools like contrast checkers can be beneficial in assessing and adjusting color pairings to meet accessibility requirements. The use of sufficient white space around text can also help to improve readability when using such a dark color.
