The color #0A4791, also known as Congress Blue, presents some accessibility challenges, particularly when used as text on a white background. Its low luminance value results in insufficient contrast, potentially making it difficult for individuals with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Congress Blue often falls short of these recommendations when paired with lighter backgrounds. To improve accessibility, consider using it for larger text elements or pairing it with a very light color like almost white or beige. Alternatively, using Congress Blue as a background with white or yellow text can also enhance readability and meet accessibility standards, ensuring a more inclusive design for all users.
