The color #213A74, also known as Astronaut, presents some accessibility considerations for web design. Its relatively dark hue results in a low contrast ratio when paired with lighter shades of gray, which can be challenging for users with visual impairments. To ensure readability and usability, it's crucial to use #213A74 with sufficiently light text colors, such as white (#FFFFFF), or lighter shades of yellow. Testing the color combination with accessibility tools is recommended to meet WCAG (Web Content Accessibility Guidelines) standards, particularly WCAG 2.1 level AA requirements. Consider using a color contrast checker to determine if the contrast ratio meets the minimum threshold of 4.5:1 for normal text and 3:1 for large text to ensure optimal readability for all users, including those with low vision or color blindness. Proper implementation will enhance inclusivity and improve user experience.
