The hex color #281dfb, a vibrant shade of blue, presents both opportunities and challenges for web accessibility. When used as a foreground color, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance.

When used for interactive elements like buttons, ensure that hover and focus states have clear visual indicators, making the interface more navigable for everyone.
