The hex color #063b61, also known as Astronaut Blue, presents accessibility challenges due to its dark nature. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Using #063b61 with dark text will likely fail these guidelines, making content difficult to read for users with visual impairments. Therefore, careful consideration and contrast checking are crucial when implementing this color in web design to maintain accessibility standards and provide an inclusive user experience. Tools are available to check color contrast ratios to ensure compliance with accessibility standards.
