The hex color #0D478A, also known as Congress Blue, presents some accessibility challenges, particularly when used as a foreground color on a white or light background. Its low luminance value (relative to pure white) results in a low contrast ratio, potentially failing WCAG (Web Content Accessibility Guidelines) standards for text readability. For instance, normal-sized text (smaller than 18pt) may not meet the minimum contrast ratio of 4.5:1 required for WCAG AA compliance. To improve accessibility, consider using #0D478A with lighter background colors that provide sufficient contrast. Alternatively, if #0D478A is the background, use a very light color like white or a very pale yellow for the text. Tools like contrast checkers can help determine if the color combinations meet accessibility standards, ensuring content is usable for people with visual impairments.
