The color #0B3D61, also known as Astronaut Blue, presents some accessibility challenges due to its relatively low luminance. When used as a background color, it's crucial to ensure that the text layered on top has sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using a light color like white or a very pale yellow for text on this background can significantly improve readability. Tools like contrast checkers are invaluable for verifying compliance. For users with visual impairments, providing alternative styling options or a high-contrast mode can greatly enhance their experience. Remember that color should not be the only means of conveying information; use text labels or icons as well.
