The color #233C75, also known as Astronaut, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low lightness value (Luminance 0.03) means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) against its background. When using #233C75 for text or interactive elements, lighter colors such as whites, yellows, or very pale blues should be used as background colors to ensure sufficient contrast. Tools like contrast checkers can assist in verifying compliance. Additionally, avoid relying solely on color to convey information; supplement with text labels or icons to accommodate users who may not perceive the color accurately. Ensuring proper focus indicators for interactive elements is also crucial for keyboard navigation.
