The hex color #0D488E, also known as Congress Blue, presents some accessibility challenges, particularly when used for text or interactive elements. Its relatively low luminance value of approximately 0.024 means that it requires careful consideration of contrast ratios to ensure readability and usability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text (18pt or 14pt bold) against its background. When using #0D488E, pairing it with very light colors like white (#FFFFFF) or very pale yellows can help achieve an acceptable contrast ratio. Avoid using it with darker shades or colors with similar luminance values, as this can lead to text that is difficult or impossible to read. For interactive elements, sufficient contrast is crucial to ensure that users can easily identify and interact with buttons, links, and other controls. Implementing accessibility testing with tools and assistive technologies is recommended to validate color choices and ensure that content is accessible to all users.
