[PIAA REF]

since the home team must wear white their arm sleeves, leg sleeve, tights, knee pads can only be white, beige, or black. The must match if wearing both arm sleeves and tights or knee pads or leg sleeve and all teammates have to wear the same color. The away team also follows that but can also wear predominate color arm/leg sleeve, tights, knee pads of their jersey.
If players are wearing wrist bands and head bands color rule, logo rule applies and wrist band and head bands must match in color and teammates must all wear same color. Head bands and wrist bands do not have to match color of leggings and arm sleeves. So home team could all wear black arm sleeves and black tights and white wrist bands and white head bands.
