A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. If used for interactive elements like buttons or links, clear visual cues beyond color alone are necessary, such as borders or underlines, to ensure usability for individuals with color vision deficiencies. Careful consideration of color pairings is crucial to avoid excluding users with visual impairments. Testing with accessibility tools is highly recommended to validate compliance with accessibility standards.
