The color #0B4F8D, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white background. Its relatively low luminance contrast ratio means that users with visual impairments may find it difficult to read. 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 (14pt bold or 18pt regular). Congress Blue may not meet these requirements, so it's advisable to use it for larger text elements or graphical elements where readability is less critical. When using this color for text, consider pairing it with a very light color like white or a bright yellow to ensure sufficient contrast. Also, avoid using it for crucial information or calls to action without a high contrast background.
