The color #0D398A, also known as Congress Blue, presents some accessibility challenges. Its dark hue results in a low contrast ratio against standard white backgrounds, potentially making text difficult to read for users with visual impairments. To improve accessibility, it's recommended to pair this color with very light shades of yellow, white, or other pale colors to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is suggested for normal-sized text and 3:1 for large text (14 points bold or 18 points regular) to meet WCAG (Web Content Accessibility Guidelines) AA standards. For AAA compliance, strive for a contrast ratio of 7:1. When using Congress Blue for interactive elements, ensure that hover, focus, and active states have sufficient contrast and are easily distinguishable.
