The color #190FA4, also known as Ultramarine, presents some accessibility challenges due to its dark nature. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Ultramarine's darkness means that only a limited range of light colors will provide adequate contrast. It's crucial to test color combinations using accessibility tools to verify compliance. Moreover, avoid using this color for crucial interactive elements without clear visual cues, as users with visual impairments might struggle to identify them. Careful consideration of font size, weight, and additional styling is necessary to enhance readability and ensure an inclusive user experience.
