The hex color #004c98, also known as Congress Blue, presents some accessibility challenges, especially when used as text against a white background. Its relatively low luminance value of 12 makes it difficult for individuals with visual impairments to perceive clearly. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Congress Blue often falls short of these ratios with lighter backgrounds, requiring careful consideration of text size and weight. To improve accessibility, consider pairing it with lighter, contrasting colors like white or yellow for text, or using it for larger graphical elements where readability is less critical. Always test color combinations with accessibility tools to ensure sufficient contrast for all users.
