The color #0D478B, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white or light background. Its low luminance value of approximately 12.5 results in a contrast ratio of about 4.1:1 against white, which is below the WCAG (Web Content Accessibility Guidelines) recommended minimum of 4.5:1 for normal text. This means that individuals with moderate visual impairments may find it difficult to read text displayed in this color. To improve accessibility, it's recommended to use Congress Blue with larger text sizes or bolder fonts, which can effectively increase readability. Alternatively, pairing it with a lighter background or using it for decorative elements rather than essential text can mitigate accessibility concerns. Ensuring adequate contrast is crucial for inclusivity and a better user experience.
