colors do not change when switching display states??

ALRIGHT, SO I HAVE A MACHINE WITH A CURRENT COLOR OF GREEN. I WOULD LIKE TO BE ABLE TO CHANGE THE OVERALL COLOR QUICKLY TO SHOW THE VARIOUS COLORS WE OFFER. SO WHAT I DID WAS CREATED A NEW DISPLAY STATE WITH A NAME OF THE COLOR I WOULD LIKE. SO TO TEST THIS OUT I CHANGED TO THE DISPLAY STATE, MADE MY COLOR AND THEN APPLIED IT TO A PART WITHIN MY ASSY. I ALSO CHOOSE "SPECIFIY DISPLAY STATE" SO THAT I KNOW ITS ON THAT ONE. HOWEVER I CAN SWITCH BETWEEN THE DISPLAY STATES AND NOTHING CHANGES. THE NEW COLOR I JUST ADDED DOESNT SWITCH BACK TO THE OLD ONE LIKE I WOULD WANT IT TO. IS THERE ANOTHER STEP I HAVE TO PREFORM? WHEN I ADD THE COLOR IM CHOOSING THE TOP LEVEL IN MY ASSY, IM ASSUMING ITS CORRECT TO DO THAT. CAN ANYONE HELP OUT???
