No, Toothless' fire is blue, just when it flies through the air it cools down and turns it into purple color as purple is not as hot as blue fire. There is NO magnisiam or any other fire than blue flame. How the blue fire is created; creating fire consist of oxygen, fuel, and high temperature. The Night Fury's fire is created with oxygene, as the descriptions said acetylene and OXYGEN charges, the fuel source is the green gas, as shown in the first film as he was about to kill Stoick. The gas MUST BE EXTREMELY HOT in order to create BLUE fire. That creates the fire, acetylene circles the fireball, and finally the plasma blast as an electricity made core which is said to be true. When Toothless fired the blast and it exploded without hitting impact, basically because Carbon dioxide is abundant at high altitude and takes away the oxygen source thus shuts the flame and the blast explodes.

Just saying the BLUE fire is VERY VERY hot, simply only proof and reasonable answer is that the gas MUST BE VERY VERY HOT.

Thx for the reply, you actually got me to find the solution. Ignore "This is FAKE" for the Brainiac experiment and watch both videos. I was looking for a biological and chemical solution to why NightFuries in particular have the Purple color. Biologically, a lot of birds and even bats produce what would be saltpetre from their dung. Depending on what they eat and what they excrete, the resulting dung would have a high concentration of Potassium Nitrate for Guano and it's a prime ingredient for gun powder. Chemically, Potassium Nitrate is used not only for gunpowder but also in fireworks. Purple is the usual flame colour of Potassium but if the pure element is mixed with water, it creates green gas. This proves that Toothless must have some Potassium Nitrate or saltpetre in his body to produce the purple color not because the original igniting fire is blue due to the oxyacetylene reaction but that the fire breath has a lot of Potassium in it. Also it seems like Toothless can vary the amount of Potassium in his fire as we saw that he can make a very bright blue oxyacetylene fire to make his bed without the Potassium and that putting a lot of Potassium in that fire breath gives it the explosive component when it's used against its target.
