The color #1C4976, also known as Chathams Blue, presents some accessibility considerations. Its relatively dark hue means it generally provides good contrast when used with lighter colors, such as white or very pale yellows, making it suitable for text and interactive elements. However, it's crucial to verify the contrast ratio using a tool like the WebAIM Contrast Checker to ensure it meets WCAG (Web Content Accessibility Guidelines) standards, particularly Level AA (minimum) or Level AAA (enhanced). Insufficient contrast can make content difficult to read for users with low vision or color blindness. Avoid pairing it with other dark colors, as this will likely fail contrast checks. When using it for links or interactive elements, ensure there's sufficient visual distinction beyond color alone, such as underlines or icons, to cater to users who cannot perceive color differences. Proper consideration of color blindness simulations during the design process is highly recommended.
