The hex color #1A037A, a deep blue, presents significant accessibility challenges. Its low lightness value (very dark) means it requires extremely light text colors to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. Using black or dark gray text on a #1A037A background would undoubtedly fail these criteria. White or very light shades of yellow or green are better options, but careful testing with accessibility tools is crucial. Insufficient contrast can exclude users with low vision or color blindness. Also, avoid using this color as the sole means of conveying information, as users with color vision deficiencies may not perceive it correctly. Ensure sufficient text size and weight for readability.
