The hex color #2B3B6D, also known as Astronaut, presents some accessibility challenges, particularly in text applications. Its relatively low luminance value of 0.11 means that it requires careful consideration of contrast ratios. When used as a background color, it's crucial to pair it with light-colored text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for larger text (14pt bold or 18pt regular) to meet WCAG AA standards. Insufficient contrast can significantly hinder users with visual impairments or color vision deficiencies. Designers should use color contrast checkers to verify compliance. Alternatively, using this color for decorative elements rather than functional text might mitigate accessibility concerns. Careful attention to context and purpose is essential when incorporating #2B3B6D into designs.
