The hex color #00539c, also known as Endeavour, presents some accessibility considerations, particularly in web design. Its dark hue means that it requires careful pairing with lighter colors to ensure sufficient contrast for readability. 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. Using #00539c for text on a white background may not meet these standards and could pose challenges for users with visual impairments. To improve accessibility, consider using #00539c sparingly for decorative elements or pairing it with very light text colors such as white (#FFFFFF) or a light shade of yellow to guarantee sufficient contrast. Always test color combinations with accessibility tools to verify compliance.
