The hex color #17019A, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires careful selection of foreground text colors 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 standards. Using white text on this dark blue can achieve acceptable contrast, but lighter shades of gray or other colors may not. It's crucial to test color combinations with accessibility tools to guarantee compliance. Furthermore, avoid using #17019A to convey important information without additional cues, such as icons or labels, as individuals with color vision deficiencies may struggle to distinguish it from other dark colors. Consider providing alternative visual or non-visual cues to enhance accessibility for all users.
