The color #243E77, also known as Astronaut, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a background color, it's crucial to ensure that any text or foreground elements layered on top of it have sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Tools like contrast checkers can help verify compliance. Consider using a lighter color for text, such as white or a very light gray, to maximize contrast. Additionally, avoid using this color for interactive elements without clear visual cues, as users may struggle to differentiate them from static content. Providing alternative styling options, such as a high-contrast mode, can further enhance accessibility.
