The Copyleaks duplicate content checkers use different color highlights for their readers, and each color has a specific meaning, and those are: Red: The text is identical. Light Pink: Minor changes were made compared to the original source from where the content is taken. It needs to be changed, and entirely original content should be created. Yellow: The yellow color is used to denote ‘paraphrased.’ White: These are the ‘omitted words,’ in the content.
