The color #004B99, also known as Congress Blue, presents several accessibility considerations for web development. Its dark hue provides a strong contrast against light backgrounds, which is generally favorable for readability. However, when paired with other dark colors, the contrast ratio might fall below the WCAG (Web Content Accessibility Guidelines) recommended levels, particularly for users with low vision or color deficiencies. Therefore, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text when using #004B99 as a foreground color. Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey important information; supplement color cues with text labels or icons to ensure inclusivity for all users. Proper use of ARIA attributes can further enhance the accessibility of elements using this color.
