The color is relatively muted, making it a suitable backdrop for brighter accent colors.
The color #054A63, also known as Astronaut Blue, presents some accessibility challenges. Its low lightness value makes it difficult to use as a foreground color on a white background without sufficient contrast. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. This color may not meet these ratios on lighter backgrounds, potentially causing readability issues, especially for users with visual impairments. To improve accessibility, consider using #054A63 on very light backgrounds or pairing it with a much lighter foreground color to ensure sufficient contrast. Testing with accessibility tools is recommended to confirm compliance with accessibility standards.
