A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a color contrast checker is crucial to verify compliance. Avoid pairing it with dark or similarly-toned colors, as this can lead to poor readability, especially for users with visual impairments. When using this color for interactive elements like buttons or links, provide clear visual cues beyond color alone, such as underlines or icons, to ensure usability for colorblind users. Careful consideration of text size and weight can also improve readability. Ensure that any images or graphics that use this color are also accessible, with appropriate alt text for screen readers.
