The hex color #020D11, also known as Blue Charcoal, presents significant accessibility challenges. Its extremely low luminance value of 0.004 makes it difficult to read text against a white background. 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 to meet AA compliance. Blue Charcoal fails to meet these ratios against standard light backgrounds, potentially causing readability issues for users with visual impairments. To improve accessibility, consider using it sparingly, pairing it with very light colors, or increasing text size and weight significantly. Ensuring sufficient contrast is crucial for an inclusive user experience.
