The color #223F79, also known as Astronaut, presents some accessibility challenges due to its relatively dark hue. When used as a background color, it's crucial to ensure that the text or foreground elements layered on top have sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure readability for users with visual impairments. Using a lighter color for text, such as a light gray or off-white, can help achieve this. Avoid pairing #223F79 with other dark colors, as this can create a low-contrast environment that is difficult for many users to navigate. Tools like contrast checkers can be invaluable in determining whether color combinations are accessible. Consider providing alternative color schemes for users who may have difficulty perceiving the intended contrast.
