The hex color #063b5e, also known as Astronaut Blue, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value (approximately 2.9) results in poor contrast against light backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Astronaut Blue falls short of these recommendations when paired with standard white (#FFFFFF). To improve accessibility, consider using a much lighter color for text or interactive elements placed on an Astronaut Blue background, or vice versa. Evaluate the color contrast to ensure sufficient readability for users with low vision or color blindness. Tools like WebAIM's Contrast Checker can be invaluable for assessing contrast ratios and identifying potential accessibility issues.
