The color #0B0197, a deep ultramarine, presents several accessibility considerations for web design. Due to its low luminance, it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Therefore, using #0B0197 for text on a white background would fail accessibility standards. To improve accessibility, consider using it with very light colors like white (#FFFFFF) or very light yellow (#FFFFE0) to ensure readability. Also, avoid using this color for small, intricate UI elements where clarity is crucial. When used as a background color, provide sufficient padding around text and interactive elements to enhance legibility. Additionally, provide alternative styling options for users with visual impairments, such as a high-contrast mode. Remember that visual perception varies among individuals, so it's always beneficial to test color combinations with real users or accessibility evaluation tools to validate their effectiveness.
