Taylor Swift and Travis Kelce don't want the red carpet rolled out for them for their wedding event at Madison Square Garden ... they want purple carpet instead, even if workers have to start from scratch.

Our photog took this video and was told the carpet is supposed to be purple, not red ... hence the frantic change.
