The hex color #221dfb, a vibrant blue, presents accessibility challenges, particularly for users with visual impairments. Its contrast ratio against a white background is low, making text difficult to read for individuals with low vision or color blindness. To improve accessibility, consider using a lighter background color or darkening the text color to increase contrast. Tools like contrast checkers can help determine if the color combination meets accessibility standards such as WCAG. It's crucial to ensure sufficient contrast for all users to perceive content clearly. For instance, a text color with a minimum contrast ratio of 4.5:1 against its background is generally recommended for normal-sized text, and 3:1 for larger text. Providing alternative text descriptions for images and other non-text elements that use this color can further enhance accessibility.
