The hex color #281B7D, also known as Persian Indigo, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1 contrast ratio) and large text (3:1 contrast ratio). It's crucial to test color combinations with accessibility tools to avoid making content inaccessible to users with visual impairments. Avoid pairing this dark shade with other dark colors or muted tones, as this can render text illegible. When using this color for interactive elements like buttons or links, provide clear visual cues beyond color alone, such as underlines or icons, to aid users who may not be able to distinguish color differences.
