Black smoke = Fuel burning. Mixture rich.
White smoke = Coolant leaking and burning.
Blue smoke = Oil Burning. Piston rings shagged.
Some smoke from cold start is ok. If it does it when warm there is a problem, but dont forget that all exhausts emit some smoke anyway which we dont normally see. On cold days it is more obvious and tends to naturally worry people.
If your water level hasnt dropped, not burning any more oil than is normal, and your fuel ecomony isnt suffering, dont worry about it.
