The hex color #0F3C89, also known as Congress Blue, presents some accessibility challenges, particularly regarding color contrast. When using this color for text or interactive elements, it is crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet AA level accessibility. Congress Blue, being a dark shade of blue, may not provide enough contrast when paired with lighter backgrounds like white or light gray. To improve accessibility, consider using a lighter shade of blue or a contrasting color like yellow or orange for foreground elements. Also, it's beneficial to use tools like the webaim contrast checker to determine the color contrast. Remember to provide alternative cues for users who are unable to distinguish colors.
