The hex color #0A4E8E, also known as Congress Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low lightness value results in a dark appearance, which means careful consideration must be given to contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. When using #0A4E8E for text, it's essential to pair it with a light color like white or a very pale yellow to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. For user interface components and graphical objects, a contrast ratio of 3:1 is required against adjacent colors. Using color contrast tools is recommended to verify compliance with these guidelines and ensure that content is accessible to all users. Additionally, avoid using color alone to convey important information; use text labels or other visual cues to supplement color coding.
