What colour should I paint the studio floor?

It always makes me chuckle when the topic comes up on Clayart about what kind of paint to use or what colour to paint the studio floor. Check out these swanky studios in China. Put on your gum boots you're going to work and heck ya never know when you'll see a cute sheep. These guys are throwing about 80-100 lbs of clay in tandem. The guy in the orange is the obvious leader and the other guy is literally support staff.
Check out the floor! It is one big mucky bog. Here are the pots that the two guys threw today and they have 3 or 4 more hours to work. You're probably looking at 4 or 5 tons of clay. No complaints about carpal tunnel! As Denny at USU would say " It ain't gay, it's survival!"
