The color #0F21C7, also known as Persian Blue, presents several accessibility considerations for web developers. Its relatively low luminance can pose challenges for users with visual impairments. When using this color for text, it is crucial to ensure a sufficient contrast ratio against the background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For WCAG AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Using online contrast checkers can help verify compliance. Avoid pairing #0F21C7 with similar dark shades, as this will reduce readability. Providing alternative color schemes or allowing users to customize colors can further enhance accessibility. When using this color for interactive elements, such as buttons or links, ensure sufficient visual cues beyond color alone to indicate the interactive state. Consider using underlines, borders, or icons to provide additional confirmation to users.
