The color #004098, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white background. Its relatively low luminance value of approximately 6% means it offers limited contrast. 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 visual impairments. Congress Blue falls short of these recommendations when paired with light backgrounds. To improve accessibility, consider using it for larger text elements, or pairing it with lighter colors such as yellows, oranges or whites. Also, using it as a background color with white text is preferable and will pass WCAG compliance. Providing sufficient contrast ensures that content is perceivable to a wider audience, including those with low vision or color blindness. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility standards, ensuring a more inclusive user experience. Remember to test the color combinations on real devices to ensure that they are properly displayed and accessible.
