When used as a background color, it's crucial to ensure that any text or interactive elements layered on top have sufficient contrast to be easily readable by individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using Congress Blue, lighter colors like white, light yellows, or pale greens could provide acceptable contrast. Tools such as WebAIM's contrast checker can be used to verify compliance. Furthermore, avoid using this color as the sole means of conveying information, as colorblind users may not perceive it accurately. Always provide supplementary cues, such as text labels or icons, to ensure inclusivity.
