Blue is also characteristic of heavy oil burning. White can be coolant (not applicable here), excessive fuel (vapor mist), water contamination or just a really cold day condensing the water vapor in the exhaust.
Grey can indicate fuel burning in the exhaust (incomplete) or light oil burning. Usually you can also smell which of the two it is. Black is soot, oil or fuel. Fuel burning /in/ the exhaust will produce black smoke. Again, you can smell which one it is.
