The hex color #213A7B, also known as Astronaut, presents some accessibility challenges, primarily due to its dark nature. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color may not meet these ratios with many common text colors, necessitating careful selection of contrasting foreground elements. Designers should use contrast checking tools to verify compliance with accessibility standards. Additionally, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons are crucial for users with color vision deficiencies. Thoughtful consideration of these factors can help ensure that content using #213A7B is accessible to a wider audience.
