Does the black iphone 5S look more professional?

I know it's just a matter of colour and its not really important, but I was curious wether business people would choose black iphones over white iphones. Maybe it looks more serious.

What do you guys think?

Added (1). To the person who just answered:
I specifically said that I know its not important, but i would like to know what colour you prefer. I never said that you need to show off your phone to your clients. I only wanted an opinion.

Do you honestly believe that your level of professionalism can be conveyed by which phone you use? Far less the colour of such a device!

How utterly unprofessional and shallow can you be?

You know something, my clients never get to see my phone, because it gets switched off at meetings. There's nothing more unprofessional than someone fiddling with a phone, or allowing business conversations to be interrupted by a phone call.

Why are you asking in the photography section?

Yes, I would say black looks SLIGHTLY less amateurish, but no color looks "professional" if a phone is being used instead of a proper camera in an important situation.
