The color #0B3B61, also known as Astronaut Blue, presents some accessibility challenges, especially when used as text on a white or light-colored background. Its low lightness value (approximately 0.07) results in a low contrast ratio, potentially failing WCAG (Web Content Accessibility Guidelines) standards for normal text. To improve accessibility, consider using a lighter color for text or interface elements when paired with #0B3B61 as a background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help evaluate and adjust color combinations. Using #0B3B61 for purely decorative purposes, where the meaning isn't conveyed through color alone, mitigates accessibility concerns. Adding borders or other visual cues can also aid users who have difficulty distinguishing colors. Also, ensure sufficient contrast when used for interactive elements, such as buttons, to help people who have visual impairments.
