The hex color #1B3ABB, also known as Persian Blue, presents several accessibility considerations for web developers. Its relative luminance is quite low, which means it might not provide sufficient contrast when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. To ensure accessibility, it's advisable to pair #1B3ABB with light or pastel colors. When using this color for text, a contrast ratio of at least 4.5:1 against the background is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Testing contrast ratios with accessibility tools is essential. Also consider that colorblind users may perceive this color differently, so providing alternative visual cues or text descriptions can further enhance accessibility.
