The hex color #211C00, also known as Cannon Black, presents significant accessibility challenges due to its low luminance. With such a dark shade, ensuring sufficient contrast against lighter backgrounds is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended by WCAG guidelines for normal text, and 3:1 for large text. Testing the color combination with accessibility tools is essential to verify compliance. Using this color for text requires careful consideration, potentially pairing it with very light hues to achieve readability. Avoid using it for small, detailed elements as they may become indiscernible. Incorporating a focus state with a clear, contrasting outline is necessary for interactive elements to ensure keyboard navigability. The color should also not be used as the sole means of conveying information.
