The color of the smoke depends on mainly two factors. The type of fuel used and whether the combustion of fuel is complete or not. If fuel used contains large amount of carbon in it then smoke is little bit sooty (black ). If the combustion of fuel is incomplete then also color of smoke  is more black.
