The color #283F71, also known as Astronaut, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) AA standards for normal text, which require a contrast ratio of at least 4.5:1. This means users with moderate visual impairments may struggle to read the text comfortably. To improve accessibility, consider using #283F71 for larger text elements (18pt or 14pt bold) or graphical objects, as the contrast requirements are slightly lower at 3:1. Alternatively, pairing #283F71 with a much lighter background color or using it sparingly in combination with brighter, more contrasting accent colors can enhance readability and ensure a more inclusive user experience. Always test color combinations with accessibility tools to verify sufficient contrast.
