The hex color #0F3A8B, also known as Congress Blue, presents some accessibility challenges, particularly when used as a background color for text. Due to its dark nature, sufficient contrast is crucial to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text against a background.
