Video Production Opinion

To moderators: I was not sure what category this one should go in, so feel free to move it if necessary:

Looking to buy some tatami mats to begin shooting catfight videos.  However, the vendor has given me a choice of color: Light grey, royal blue, fire red, bright yellow, light purple or mint green.  Which color would show up best on camera, one that lighting won't reflect so badly?  Thanks alot!
