Let's say the visiting team shows up with only their dark blue home jerseys. The R asks the home team if they can switch to the away jerseys to avoid confusion. The home team can't for whatever reason.
1-5-1-b-2 says V is responsible for wearing white jerseys that are different from the home team, but there is no penalty in that section. 1-5-3 is where V could be penalized for illegal equipment, but that rule has the following verbiage: "...which in the opinion of the umpire is dangerous, confusing or inappropriate."
So if the home team wears red jerseys, there is no confusion, and there shouldn't be a foul. Right?
