Considering that if you have black smoke your car is running too rich. Blueish white smoke from the exhaust means it burning oil. Depending on exactly where this white smoke is coming from it is most likely Transmission Fluid that is burning. A bad seal or gasket on the trans will cause it to leak. Especially when your car is hot and the tranny is shifting, this will cause more pressure on the leaks thus forcing out more fluid. This form of excessive leakage shoots out the fluid which then hits the exhaust manifold or exhaust pipe and burns up very quickly producing a thick white smoke that if your driving it seems to be coming from the tailpipe but actually is coming from the front center of the car. A good way to check is to go to a quarter car wash, spray off the bottom of the car, and any parts of the exhaust manifold or pipe. After driving for a while, and it still smokes, you should be able to see freshly burnt on stains on the exhaust system. Also don't forget to check your trans, fluid lvels.
