The color #0D4B8E, also known as Congress Blue, presents some accessibility considerations for web developers. Its darkness results in a relatively low contrast ratio when paired with standard white text. To ensure readability and compliance with WCAG (Web Content Accessibility Guidelines), it's crucial to use sufficiently light text colors like white (#FFFFFF) or very light shades of gray. For smaller text sizes, a contrast ratio of at least 4.5:1 is recommended, while larger text sizes require a minimum of 3:1. Tools are available to check the contrast ratio between foreground and background colors. Moreover, avoid using this color as the sole means of conveying important information; supplement it with text labels or other visual cues to cater to users with color vision deficiencies.
