The hex color #1d009b, a deep ultramarine, presents some accessibility challenges, especially in text applications. Its low lightness value (approximately 12%) means it requires careful consideration when used as a foreground color. To ensure sufficient contrast for readability, it's crucial to pair it with a light background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text according to WCAG guidelines. Using online contrast checkers is highly advisable to verify compliance. When used as a background, light text is essential. Moreover, avoid using this color for critical interface elements or important information without ensuring adequate contrast, as it might be missed by users with visual impairments. Semantic HTML and ARIA attributes can further enhance accessibility, providing context and meaning beyond the color itself.
