The hex color #280D8E, a deep and intense shade of blue-purple often referred to as Blue Gem, presents some accessibility considerations for web development. Given its low luminance, it's crucial to ensure sufficient contrast when used as a foreground or background color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) against its background. Using this color for text on a white background may not meet accessibility standards, so consider pairing it with lighter hues like white, yellow, or lighter shades of purple or blue to enhance readability for users with visual impairments. Also, avoid using this color as the sole means to convey information, especially for interactive elements like links or buttons. Providing additional cues, such as underlines, borders, or icons, can improve usability for all users.
