The color #234E78, also known as Chathams Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards for Level AA or AAA compliance. This means users with visual impairments may find it difficult to read. To improve accessibility, consider using a lighter background color or darkening the text color. For example, using #234E78 text on a very light yellow background (#FFFFE0) would significantly improve readability. Alternatively, use #234E78 as a background with white (#FFFFFF) or very light yellow (#FFFFE0) text to ensure sufficient contrast. When using this color for interactive elements like buttons or links, ensure sufficient visual cues beyond color alone, such as borders or text underlines, are present to aid users who might not be able to distinguish the color clearly. Always test color combinations with accessibility evaluation tools to verify compliance.
