The color #0D4A8B, also known as Congress Blue, presents certain accessibility challenges, especially concerning color contrast. When used as a foreground color for text, it is crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Due to its dark hue, #0D4A8B requires a very light background to meet these contrast requirements. Using it with darker backgrounds can make the text illegible for users with visual impairments, including those with low vision or color blindness. To improve accessibility, consider using lighter shades of blue or other contrasting colors for the background. Tools such as color contrast checkers can help assess and ensure compliance with accessibility standards.
