Why Qatar chose white over grey I don't know. Seems that small logos are permitted though as both Air India and Qatar have them.
I have trouble trying to find out why, though it is pretty logical. I guess they want to reduce the amount of layers of paint on the engine nacelle, make it as smooth as they can so the laminar flow could be maintained longer across, and therefore, reducing the amount caused by that particular area. I suppose small markings of sorts (like logos) do not disturb the airflow as much, and therefore are seen as fairly acceptable.
For those not familiar with the terminology (laminar and turbulent flow) here is a graphic that shows both of these across a diagram of an airfoil:
For those of you who spend time around smokers, it can also be observed as the smoke goes from a single, "neat" line to more unpredictable, circular flows.
Well, that is enough of a fluid dynamics lesson for now I suppose.

Hey, model plane manufactures, how about some Braniff PZL 230Fs.
