because of less oxygen.

If you heat a steel rod (with electricity?) it will glow red then orange then white hot. The color depends both on the atoms involved (iron) and the temperature. As the rod is heated, electrons orbiting the iron atoms are kicked up into higher more energetic states. When the electrons return to rest states they release excess energy in the form of photons that you can see as visible light. The color depends on how much excess energy is being released and that depends on the maximum temperature. When wood burns, the yellow color results from the photons released by electrons orbiting the atoms and molecules of the hot combustion products including carbon which is not hot enough to give off white light. Hope that helps a little.

because the wood is very dry and non-convientional source of energy.
