The hex color #103B8B, also known as Congress Blue, presents some accessibility challenges, particularly when used as a foreground color on a white background or vice versa. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. Congress Blue, being a relatively dark shade, may not always meet these contrast requirements, especially for smaller text sizes. Web developers should carefully evaluate the contrast ratio using online tools or browser extensions to verify compliance. When using Congress Blue, it's advisable to pair it with lighter colors such as white, light grays, or light yellows to ensure sufficient contrast. Furthermore, providing alternative color schemes for users with specific visual needs can significantly improve accessibility. Avoid using Congress Blue for crucial information if sufficient contrast cannot be achieved.
