That depends on what is being burned. paper for instance, burns at 451 degrees farenheir wheras things like coal burn with hotter flames.
The yellow flame? i do not know but the blue flame is 2732 degrees Fahrenheit
Oh, as far as I know, white fire is the hottest, so that leaves it in 1st place, blue 2nd, and orange in 3rd. And orange fire is the coldest you'll ever find!
A blue flame is between 8000 degrees and 10000 degrees kelvin, and if you look at the hottest stars most of them are blue.
