The hex color #213A4A, also known as Nile Blue, presents some accessibility challenges, particularly in text-based contexts. Its relatively low luminance value means that it requires careful consideration of foreground text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #213A4A as a background, pairing it with light colors such as white (#FFFFFF) or very light grays can help meet these contrast requirements. Tools like contrast checkers can be used to accurately assess the contrast ratio between #213A4A and chosen foreground colors. Additionally, avoid using this color for essential information or interactive elements without proper contrast, as it may pose difficulties for users with visual impairments. When used on interactive elements, consider using focus indicators with a high contrast ratio.
