The color #143E4B, also known as Nile Blue, presents some accessibility challenges, especially when used as text on a white or light background. Its low luminance value of approximately 0.06 makes it difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Nile Blue often fails to meet these contrast requirements with lighter background colors. To improve accessibility, consider pairing it with a much lighter color such as #FFFFFF (white) or #F0F0F0 (light gray) and testing the combination using a contrast checker. Another strategy is to use #143E4B sparingly for decorative elements rather than essential text, or implement a color palette that integrates this shade with accessible contrast ratios. Ensure sufficient contrast for interactive elements to guarantee usability for everyone.
