blue smoke is normally related to fuel problem. there is so many things that could cause this that it is best to have it checked by a technician that you trust.
Black smoke is just unburnt fuel in a diesel if the vehicle is not modified in any way to make this happen then something is causing it to not burn it all, it will not harm it but you should figure out why its not burning all of its fuel. (most diesels will spit out a little black smoke)
Blue smoke = excessive motor oil. Black smoke = excessive fuel. White smoke = engine coolant
Black smoke, from any diesel, is the result of partially burned fuel. Overfueling will cause black smoke.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
