The hex color #003F87, also known as Congress Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, sufficient contrast with text and other foreground elements is crucial to ensure readability for users with visual impairments. According to WCAG guidelines, the minimum contrast ratio for normal text is 4.5:1, and for large text, it's 3:1. Therefore, pairing #003F87 with lighter hues like white (#FFFFFF) or light yellows can help meet these standards. It's also important to avoid using it with very dark colors, as the contrast would be insufficient. When using this color in interactive elements like buttons and links, it's essential to test the contrast of the different states (hover, focus, active) to guarantee that these states are also clearly distinguishable for all users, including those with low vision or color blindness.
