The hex color #0A4191, also known as Congress Blue, presents some accessibility challenges. Its dark hue means it requires very light text for sufficient contrast. According to WCAG guidelines, using #0A4191 as a background color necessitates a foreground color like white (#FFFFFF) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, the contrast ratio should be 7:1 for normal text and 4.5:1 for large text. When using this color, ensure all interactive elements such as buttons and links have distinct visual cues beyond color alone, such as underlines or borders, to accommodate users with color vision deficiencies. Thorough testing with accessibility tools is recommended to validate compliance and ensure readability for all users.
