Scientists think that if we heat a certain body to an infinite temperature, the wavelength is zero !! that is there is no light at all, in other words there is black radiation and the resulting fire resulting from burning this body of the infinite temperature is dark black.

In fact black body radiation has a small role in the color of the flame: putting in 700nm (for blue) in the equation yields over 3500 degrees celsius while the temperature of a gas stove flame is about 1700. The colors are a result of, as was mentioned in the comments, ionization of gas molecules.
