The hex color #021bd4, a dark blue, presents significant accessibility challenges, especially for users with visual impairments. Its low lightness value results in poor contrast against common background colors like white. Text using this color should be avoided unless paired with a very light foreground color to ensure sufficient contrast ratio as defined by WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using this dark blue for interactive elements, such as buttons or links, provide clear visual cues and hover states to help users understand their function. Color alone should never be used to convey meaning; always use text labels or icons as well. Consider offering a high-contrast mode option for your website or application to cater to users with different visual needs. Careful attention to these accessibility factors will enhance the user experience for everyone.
