The hex color #0C3B8C, also known as Congress Blue, presents some accessibility challenges, particularly when used as text against a white background. Its relatively low luminance (darkness) can result in insufficient contrast, making it difficult for users with visual impairments to read. To improve accessibility, it is recommended to use #0C3B8C with lighter background colors or as a background for white or very light-colored text. Tools like contrast checkers can help ensure that color combinations meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios, typically aiming for a minimum ratio of 4.5:1 for normal text and 3:1 for large text. Considering these guidelines is crucial for creating inclusive and user-friendly designs. When this color is used for decorative purposes and doesn't convey crucial information, accessibility requirements are less strict, but thoughtful color choices are always preferable.
