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. This color fails to meet these criteria, requiring careful consideration of foreground colors. White text on a #131588 background will likely be illegible for many users, including those with visual impairments. To improve accessibility, consider using lighter shades of blue or pairing it with a contrasting color like yellow or a light pastel shade to ensure sufficient contrast. Tools like contrast checkers can help determine compliance with accessibility standards.
