The color #263F71, also known as Astronaut, presents some accessibility challenges. Its relatively low luminance can make it difficult to read text rendered in this color against a white background. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using a color contrast checker, it's crucial to ensure sufficient contrast. Consider pairing #263F71 with lighter text colors like white or very pale yellow to improve readability. Alternatively, a darker background could enhance the contrast if #263F71 is used for text. Always test color combinations to ensure they meet accessibility standards for all users, including those with visual impairments.
