Not many people would want to see black smoke coming out of their tailpipe. Having a black smoke just means that there is excess fuel in the cylinder area, and not all is being burned completely. In some other cases, this problem is called “running rich” because this issue leads to wasteful fuel burning. It is the reason most people would complain about having bad fuel economy with their cars after experiencing the black smoke.
The black smoke will have effects such as low engine performance, reduced fuel economy among many others. It is however not the biggest cause of alarm as with a few tweaks; the car should be back to normal.

Blue smoke will start coming out of your tailpipe if the engine oil enters the combustion area. The oil will then start being burned along with your fuel and air mixture found in the combustion area.
Remember that with blue smoke; even just a drop of the engine oil into the combustion area will always lead to the problem of blue smoke. People who own older or cars with a higher mileage will have such issues rather than the new models.
Whenever there is enough oil leak into a cylinder, it can fault for the spark plug. It will certainly cause an engine miss for that cylinder or a misfire. When a misfire happens, you need to get the help of your mechanic to repair it before extensive damage is done.
The answer to the question why is my car smoking with blue color:
Cracked or leaking seals

For the repairs and replacement of engine seals that prevent an oil leak, you might want to let the mechanic handle the repairs.
White smoke can be either thinner or thicker depending on the cause. The thin white smoke should not be too much alarming as compared to the thick white smoke. We can see the thin white smoke during the cold mornings during winter. It is because the engine is cold and will disappear when the engine is warm enough. If you keep getting a white smoke even on hot days, then there is a problem now.
The thick white smoke is released when there is water entering the cylinder. The engine will proceed to burn the mixture of fuel and water in the combustion area. Whenever you get such a problem, the first suspect would be the gaskets.
The gaskets are supposed to keep water or antifreeze products from entering the combustion area of the engine. With the white smoke, even the slightest amount of antifreeze or water entering the cylinder area will always lead to the white steam coming out of your exhaust.
Some special reasons why is my car smoking with white color:
Blown head gasket of the engine
Having a cracked engine block
Cases of engine overheating
With the engine overheating being among the causes, check to see if you have enough coolant in the radiator and also the overflow bottle
Check if there is antifreeze or water contaminating with the engine oil
Your engine dipstick can tell you if there is contamination of the oil with the antifreeze. If there is the engine oil appears to have a chocolate milkshake look, then it is a sign of more issues.
Do not start your car engine with such a different color is observed as it can lead to additional internal engine damage.
It is easy for a car owner to confuse between a black and gray smoke. They are almost the same in color, with one being darker than the other. We should not discount gray smoke. If it occurs, a couple of things need repairs immediately.
You might have a faulty turbocharger for those who own one

Your vehicle’s transmission vacuum modulator is faulty
