The color #1D477B, also known as Chathams Blue, presents some accessibility challenges, especially regarding text displayed against this background. Due to its relatively dark nature, it requires careful consideration of color contrast to ensure readability for all users, including those with visual impairments. A light color, such as white (#FFFFFF) or a light shade of yellow (#FFFFE0), is recommended for text displayed on a #1D477B background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. It is crucial to test the color combination with accessibility tools that measure contrast ratios to ensure compliance. Using a text color that does not provide sufficient contrast can result in a poor user experience, making it difficult or impossible for some users to read the content. Also, when used for interactive elements, the color should clearly signal the state of the element (e.g., hover, active, focus) through sufficient contrast change, ensuring that these states are perceivable to users.
