White smoke is water vapor (or coolant) in the exhaust, the black smoke is the (normal) over-rich condition at WOT (full acceleration)
White smoke can also be unburned fuel, generally seen on earlier, non-electronic engines that are mistimed.

this will happen on all diesel engines (if its going to make reasonable power) its basically soot/carbon from the exhaust and unburnt diesel. on some high power turbo diesel cars there is proper plumes of black smoke. you only need be worried if there is blue smoke while on boost as this means the turbo is shot. but black = good

The black smoke is caused by too much diesel fuel being supplied to the engine when you first open the throttle. Quite often this happens when the fuel injectors are worn and /or the turbo is not coming up to speed quick enough.
