Chlorine Trifluoride: what color does it burn?

[Rater202]

It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

Describing Chlorine Trifluoride, one of the most flammable substances known, a better oxidizer than pure oxygen, able to instantaneously ignite sand, water, ashes and pretty much anything that we normally think of as fireproof.

But what color is it? The fire that forms when this substance burns? Is it like ordinary fire or does fluorine and/or chlorine color the flame?

Because I cannot for the life of me find out what color it burns.

It's a pretty poor quality video, unfortunately, but this is showing the result of putting the stuff on various things--from what I can tell, it seems to mostly be a yellowish-white flame, although I possibly saw a green tint at one point that I'm not sure of:

IIRC thencolor of a flame generally depends on the fuel and the temperature, so you'd have to answer that as well before an answer could be given
