[AZ-Observing] Scope Color

Does anyone have any experience or notice a difference in observing  
based on the color of one's telescope tube?  I know white reflects  
the most amount of light and should therefore remain cooler as day  
drops to night, thus probably eliminating tube currents, but stands  
out like a sore thumb at night.  Black would be the ideal color for  
nighttime observing, but if your were to leave it in the daylight,  
inner tube conditions maybe effected for part of the night, as well  
as the mirror.  And these are both the extremes.

Am I just splitting hairs here (obviously not to make cross hairs),  
or are there any studies on this?  Anyone have experience in this  
situation?  Ultimately, I am repainting my ten's aluminum tube and  
weighing between aesthetics and functionality.  Of course, I could  
get the best of both worlds in terms of functionality and paint the  
tube white and the focuser area black.
