I tried to pay more attention to my opponents movements while playing yesterday. Then this thought came to mind -- it would be much harder to see them in my pheriperal vision if the color of their clothes blend to the to sorroundings. Does anyone use camouflage in badminton? Is there any rule in badminton to prevent camouflage?
I think your eyes are more sensitive to movement than camo. There was a test done that someone showed you a video of a forest with some marines in camo hidden and you could not spot them (at least I couldn't). But the moment they moved a little you saw them right away and would always spot them if they were in the relative area when they were still. They explained that as long as the person was perfectly still camo works, but once they moved and your eyes spotted it (and they are very good at it) you will always see them.
