The color #153C54, also known as Nile Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, if used for text, consider pairing it with a lighter background or using a lighter shade of blue or a completely different color to ensure readability for all users. When using this color for interactive elements, such as buttons or links, ensure sufficient contrast with the surrounding elements and provide clear visual cues like hover effects to aid usability. The color should not be the sole indicator of the content or function. Always test the color combination with accessibility tools to guarantee compliance.
