The hex color #0b4a8d, also known as Congress Blue, presents some accessibility challenges, particularly regarding color contrast. When used for text or interactive elements, it's crucial to ensure sufficient contrast against the background. A light background color is highly recommended to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Tools like WebAIM's Contrast Checker can help verify compliance. Additionally, avoid relying solely on color to convey information; supplement it with text labels or other visual cues to accommodate users with color vision deficiencies. Consider using a lighter shade of blue or a completely different color palette to improve accessibility for all users. Thorough testing with different color vision simulations is essential during the design process.
