The color #0B188D, a deep shade of ultramarine, presents several accessibility considerations for web design. Its dark hue results in a high contrast ratio against white text, generally exceeding WCAG (Web Content Accessibility Guidelines) requirements for normal text (4.5:1) and large text (3:1), making it suitable for headers and body text on light backgrounds. However, when used with dark text or on dark backgrounds, the contrast might fall below acceptable levels, causing readability issues, especially for users with visual impairments. Ensuring sufficient contrast is crucial. Also, avoid using this color as the sole indicator of interactive elements like links; always provide additional cues such as underlines or icons for those with color blindness. Proper color contrast analysis using tools such as the WebAIM contrast checker is recommended during the design process.
