The color #1530B5, also known as Persian Blue, presents certain accessibility challenges, especially when used as a foreground color on a white or light background. Its relatively low luminance value (approximately 0.11) means that the contrast ratio might not meet the WCAG (Web Content Accessibility Guidelines) requirements for text legibility. Specifically, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). When using Persian Blue for text or interactive elements, careful consideration must be given to the background color choice to ensure sufficient contrast. Lighter shades of yellows, greens, or oranges could potentially provide better contrast. Additionally, providing supplementary cues like icons or text labels can further enhance accessibility for users with visual impairments. Testing with accessibility tools is crucial to validate the color combination and overall design.
