The color #033A63, also known as Astronaut Blue, presents several accessibility considerations for web design. Its low lightness value (approximately 11%) results in a very dark appearance, which means it requires careful attention to color contrast. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. When using #033A63 as a background color, it is imperative to use very light text colors (e.g., whites or very light yellows) to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools are available to test color contrast ratios. Avoid using #033A63 for small text or icons against dark backgrounds, as this can make content illegible for many users. Providing alternative high-contrast themes can also improve accessibility.
