The color #0B3BBF, also known as Persian Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color against a white background, it may not provide sufficient contrast for users with visual impairments, potentially making text difficult to read. To ensure accessibility, it's crucial to use this color with a lighter background, such as white, or pair it with a much darker foreground color to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Furthermore, avoid using #0B3BBF for crucial interactive elements without additional visual cues like underlines for links or borders for buttons, ensuring all users can perceive and interact with your content effectively. Testing with accessibility tools is advisable.
