A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure compliance and provide a comfortable experience for users, including those with visual impairments. Designers should use tools to verify contrast ratios and conduct user testing to ensure the color scheme is accessible to a wide range of users.
