Ask HN: Does the Herman Miller Mirra 2 white frame get dirty easily?

I'm about to buy a Herman Milla Mirra 2 chair and am stuck between two color schemes.

The first, safe option is all black for ease of maintenance sake. I wouldn't really have to worry about visible stains and discoloration over time and could be a little more "reckless" with it, if you will.

The second option, the one I really want, is black back & seat with a white frame (http://imgur.com/a/oJ7ti). My only concern with this scheme is the amount of upkeep it might take to keep it clean. I plan on keeping this chair for years to come, so that's why the amount of maintenance plays a big role.

Does anyone have experience with a white Mirra 2? Do they get dirty easily or am I being ridiculous?

...I just want to make sure I get something I'm happy with. Any advice would be much appreciated.
