It's surely not an advantage if you're playing against me!
I know when I play tennis, if an opponent is wearing something red, I do seem to hit a disproportionate number of balls at them
- it's almost as if my eye is riveted to the red, like a target, and can't see another thing. I've noticed this many times in myself - not sure if it affects others. I spend a lot of time apologising. I'm always quite sensitive to colour, though.
Consequently, I never wear red on a tennis court - just in case others are affected the same way.
