The hex color #004c7f, also known as Congress Blue, presents some accessibility challenges primarily due to its relatively low lightness value. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet AA compliance. For optimal accessibility (AAA compliance), the contrast ratios should be even higher (7:1 and 4.5:1, respectively). Using online contrast checkers is highly recommended to verify the contrast ratio against chosen background colors. Avoid pairing #004c7f with similarly dark colors, as this will make content difficult or impossible to read for users with visual impairments. Lighter shades of grays, yellows, or even desaturated blues and greens can provide adequate contrast. When using this color for interactive elements like buttons or links, ensure that hover, focus, and active states have sufficient contrast as well.
