The hex color #2B159F, also known as Blue Gem, presents some accessibility challenges, particularly when used as a foreground color against a white or light-colored background. Due to its relatively low luminance, the contrast ratio may not meet the WCAG (Web Content Accessibility Guidelines) requirements for text legibility. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #2B159F for text, it's crucial to pair it with a very light background to ensure readability for users with visual impairments. For interactive elements like buttons or links, consider using a lighter shade of blue or a contrasting color for the text to enhance usability. Adequate testing with accessibility tools is essential to validate color choices and ensure they meet the needs of all users.
