Tools like contrast checkers can help verify compliance. Using this color for interactive elements, such as buttons or links, requires careful consideration of visual cues to ensure users can easily identify and interact with them. Pairing it with a much lighter color for text or UI elements can improve readability and usability for individuals with visual impairments. If used as a background, consider using lighter foreground elements. Always prioritize testing with users to ensure the color choices meet their needs.
