The hex color #003F5E, also known as Astronaut Blue, presents some accessibility challenges. Its relatively low lightness value (around 12%) means that it requires careful consideration when used as a background or foreground color. According to WCAG guidelines, it's crucial to ensure sufficient contrast between text and background colors to make content accessible to users with visual impairments. When using #003F5E for text, opt for very light colors like white or pale yellow to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid pairing it with darker colors as this can make the text illegible. For decorative purposes, less stringent contrast rules apply, but it's always better to err on the side of caution. Proper color contrast benefits all users, not just those with visual impairments. Using online contrast checkers can help determine if your color choices meet accessibility standards.
