The hex color #013F5D, also known as Astronaut Blue, presents some accessibility challenges, especially when used as a background color for text. Its dark hue means that only very light text colors will provide sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #013F5D, ensure that the text color is carefully chosen and tested with contrast checking tools. Considering its low lightness value, it's best paired with colors like white, light gray, or very pale yellow to ensure that users with visual impairments can easily read the content. It's essential to avoid using this color for small text or important interactive elements without proper contrast.
