The hex color #131888, a deep ultramarine, presents significant accessibility challenges. Its very low luminance means that text rendered in this color against a white background will have extremely poor contrast, failing WCAG guidelines for readability. To improve accessibility, consider using lighter text colors like white or very light grays on top of #131888. Alternatively, use #131888 for large graphical elements where text contrast is not a primary concern. When using #131888 as a background, ensure foreground elements have sufficient contrast. Tools like contrast checkers can help evaluate color pairings. Also, avoid using this color to convey critical information without providing redundant cues, such as icons or labels, as users with color vision deficiencies may not perceive it accurately. Always test color combinations with accessibility in mind to ensure content is usable by everyone.
