The hex color #104D8B, also known as Congress Blue, presents some accessibility challenges, primarily related to contrast. When used as text on a white background, or vice versa, the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards for Level AA or AAA compliance. This means that users with visual impairments, such as low vision or color blindness, may find it difficult to read text or distinguish elements using this color. To improve accessibility, consider using a lighter shade of blue or a contrasting color such as yellow or white for text on a Congress Blue background, or a darker shade for the background if Congress Blue is used for the text. Tools like contrast checkers can help ensure sufficient contrast ratios for readability. Additionally, avoid relying solely on color to convey important information; use text labels or icons to provide alternative cues for users who may not be able to perceive the color effectively. When #104D8B is used for interactive elements such as buttons or links, ensure sufficient visual cues are provided to indicate their interactive nature, especially for users with cognitive disabilities.
