   It looks like a homework or a school test question   
   and you want others to do it for you. I do not play like that.   
      
   Make a basic Google research   
   and come back with results, if the questions still persists.   
      
   If you had a basic knowledge about nitrogen chemistry   
   you would know what caused the color and how to remove it.   
      
   ( Unless the solution has a history   
   that says otherwise about the red color nature )
