The hex color #1C456B, also known as Astronaut, presents some accessibility challenges, particularly in text applications. Its relatively low luminance value (around 11%) means it needs careful pairing with contrasting colors to ensure readability. When used as a background, white or very light shades of yellow or green are recommended for text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. For small text, a contrast ratio of at least 4.5:1 is required, while larger text elements need a minimum of 3:1. Additionally, avoid using this color alone to convey critical information, as users with color vision deficiencies may struggle to differentiate it from similar hues. Consider providing supplementary cues, like icons or text labels, to enhance clarity for all users. Proper implementation of ARIA attributes can also improve accessibility for screen reader users. Ensure interactive elements using this color have sufficient visual focus indicators to aid keyboard navigation.
