The hex color #1B009B, a deep ultramarine, presents accessibility challenges. Its dark nature means it requires careful consideration when choosing text and background color combinations. For text, pairing it with a light color like #FFFFFF (white) or #FAF9F6 (eggshell) is essential to ensure sufficient contrast for readability, aiming for a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. In user interfaces, using #1B009B for interactive elements like buttons or links necessitates a clear visual distinction upon hover or focus, such as a color change or an added outline, to aid users with visual impairments. Avoid using it as a background color with dark text, as this will create a low contrast and will be hard to read. Testing color combinations with accessibility tools is crucial to guarantee compliance and inclusive design.
