There is also white fire but that is from a flame that is hotter than orange fire, which would look kind of weird (people would mistake it for holy or something )
(Hot)Red/Orange > Blue > White (Hottest).. The bunsen burner has orange and blue fire because the Blue fire has high oxygen involved, so its pure burning, compared to incomplete burning(orange) producing soot.
