Different temperatures have different frequencies. The shorter wave lengths are blue and the longer wave lengths are red.

Fire as you see it is the energy given out in the form of light, when something burns.
And depending upon what is burning, and how hot it is, the rate at which the energy is given out varies. A hotter substance gives off energy much faster. Different substances have characteristic colors of burning (which is what is used for the various colors in fire-works)..

The colour of fire can depend on many things.One reason is that as the temperature increases the frequency changes thereby changing the colour as colour depends on the frequency.
The other reason is that different substances burns with different colours.

Typically, fire comes from a chemical reaction between oxygen in the atmosphere and some sort of fuel (wood or gasoline, for example). Of course, wood and gasoline don't spontaneously catch on fire just because they're surrounded by oxygen. For the combustion reaction to happen, you have to heat the fuel to its ignition temperature.
From different chemical reaction, thus different colours appear.

this is due to the temperature of the fire, and what is being consumed by it
