To ensure accessibility, it's crucial to pair this color with a significantly lighter color for text or other foreground elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Consider using online contrast checkers to verify compliance. For backgrounds, ensure sufficient contrast with foreground elements like icons or interactive components. When used in charts or data visualizations, provide alternative cues like labels or patterns to differentiate elements for colorblind users. Thoughtful application is key to inclusive design with Astronaut Blue.
