The hex color #0A4491, also known as Congress Blue, presents some accessibility challenges, particularly when used as text against a white background. Its relatively low luminance value of 14 results in insufficient contrast, failing to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and even large text (AA). A contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. To improve accessibility, consider using #0A4491 for larger graphical elements or pairing it with lighter background colors like whites, light grays, or pale yellows. When using #0A4491 for text, ensure a significantly lighter text color is used to achieve sufficient contrast and adhere to accessibility best practices. Tools like contrast checkers can help you verify and adjust color combinations to meet accessibility standards, promoting inclusivity and usability for a broader audience.
