The color #0A448E, also known as Congress Blue, presents some accessibility challenges, especially when used for text. Its relatively low luminance of approximately 5% means that it requires very light text to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0A448E as a background, ensure text is white or a very light shade to meet these contrast requirements. Avoid pairing it with darker colors as text, as this can cause visual strain. In interactive elements, consider providing alternative visual cues, like borders or icons, in addition to color to ensure usability for users with color vision deficiencies. Thoughtful application will ensure content is accessible to a broader audience.
