The hex color #210B8F, also known as Blue Gem, presents significant accessibility challenges, particularly for users with visual impairments. Its low lightness value results in poor contrast against common background colors like white, making text and interface elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Blue Gem typically falls far short of these recommendations, potentially excluding users with low vision or color blindness. To improve accessibility, consider pairing Blue Gem with much lighter colors or using it sparingly for decorative elements rather than essential content. Also avoid using it for interactive elements like links or buttons without sufficient contrast to indicate their interactive state. Testing with accessibility tools can help ensure compliance with accessibility standards and provide a better user experience for everyone.
