The color #0F4D93, also known as Congress Blue, presents some accessibility challenges, particularly when used as text on a white or light background. Its relatively low luminance value of 0.05 means that it doesn't provide sufficient contrast for users with visual impairments, as defined by WCAG (Web Content Accessibility Guidelines). To improve accessibility, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). When using Congress Blue, consider pairing it with lighter colors such as whites, creams, or very pale yellows to meet these contrast requirements. Alternatively, use a darker shade of the color for background if the text color is set to a light color. Tools like contrast checkers can help verify compliance. Also, avoid using #0F4D93 for essential information, links, or interactive elements without sufficient contrast, as this can severely impact usability for a significant portion of users. Providing alternative text descriptions for images and icons is always recommended.
