The color #0B398D, also known as Congress Blue, presents some accessibility challenges, particularly in text-based contexts. Due to its relatively dark hue, it necessitates careful consideration of contrast ratios when paired with other colors, especially white or lighter shades. To ensure readability and usability for individuals with visual impairments, including those with low vision or color blindness, it is crucial to maintain 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 as a background color, pairing it with light-colored text is essential. Conversely, if used for text, a very light or white background is recommended. Avoid using Congress Blue for small details or icons without sufficient contrast, as this can make them difficult to discern. Tools like contrast checkers can help verify compliance with accessibility standards such as WCAG guidelines.
