The color #1A3574, also known as Astronaut, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value (brightness) means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability. For small text, a contrast ratio of at least 4.5:1 is recommended, while large text needs a ratio of 3:1. Using #1A3574 as a text color on a white background may not meet these standards, making it difficult for some users to read. To improve accessibility, consider pairing it with a much lighter color for text or using it sparingly for decorative elements. Employing tools that check contrast ratios can help ensure compliance with accessibility standards and enhance the user experience for everyone.
