The color #10428A, also known as Congress Blue, presents some accessibility challenges. Its dark hue results in a low contrast ratio against standard white backgrounds, potentially making text and user interface elements difficult to read for individuals with visual impairments. To improve accessibility, consider using a lighter color for text or interactive elements placed on a #10428A background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG guidelines. Utilizing online contrast checkers can help verify the compliance of color combinations. Moreover, providing alternative styling options for users, such as a high-contrast mode, can greatly enhance the usability of content for a broader audience. Ensure sufficient color contrast to accommodate users with low vision or color blindness, adhering to accessibility best practices.
