The color #311A81, also known as Persian Indigo, presents certain accessibility challenges, particularly regarding text contrast. When using this color as a background, it's crucial to select a foreground text color that provides sufficient contrast to ensure readability. White (#FFFFFF) or a very light gray are generally good choices. Tools like WebAIM's contrast checker can be invaluable in verifying that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum ratio of 4.5:1 for normal text and 3:1 for large text. Also, consider users with visual impairments who may have difficulty distinguishing between similar shades, so avoid pairing this color with other dark or muted colors without proper contrast. Ensure that interactive elements using this color have clear visual cues to indicate their state (e.g., hover, focus).
