The color #1C517F, also known as Chathams Blue, presents moderate accessibility challenges. Its relatively dark hue means that it requires careful consideration when used as text or as a primary background. For text, it is essential to use a light color, such as white or a very pale yellow, to ensure sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When used as a background, pairing it with lighter elements can help balance the visual weight and improve the overall user experience. Designers should also avoid using this color for small, interactive elements unless the contrast is carefully managed to ensure they are easily discernible by users with visual impairments. Testing with accessibility tools is crucial to validate the color's usability across different user groups and devices.
