The color #183D52, also known as Nile Blue, presents some accessibility challenges, especially when used for text. Its relatively low lightness value (around 15%) means that it requires a very light foreground color 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. When using #183D52 as a background, it is crucial to test the contrast ratio with the intended text color using online tools or accessibility checkers. Avoid pairing it with darker shades, as this can make the text illegible for users with visual impairments. Consider increasing the font size or using a bolder font weight to improve readability. Providing alternative color schemes for users with specific needs can also greatly improve the accessibility of your design. Ensuring sufficient contrast is not only beneficial for users with disabilities but also enhances the overall user experience.
