The Libero in Volleyball is like a GoalKeeper in Soccer, The Libero is the most skilled defender in Volleyball. And in the rules of volleyball the Libero must wear a contrasting outfit to the team
If you mean that someone is wearing a different color that is because there is a player called a Libero who is a defensive specialist that can come in and out of the game for defensive purposes but does not count as a substitution. They wear a contrasting color top to distinguish themselves from the rest of the players.
blue jeans
The person with the different colored shirt is usually the best defensive player on the team, and us called the libero.
black, white, or dark blue if you're awesome
You can really wear almost any color since it's such a neutral color, except other neutral colors! I recommend pink
blue flats
Orange pants? Uh.. you maybe should where a different color of pants, black or white are the only real colors that will match, unless your favorite sports team has orange, then you can get a shirt with their color that will match. :D
Tree Top Piru is typically associated with the color red, as it is a set of the Bloods street gang.
The goal keeper must wear a jersey distinguishable from his team and the opposing team. This is almost always interpreted to mean he must wear a different color.
none. you should wear no top.
depends on what colour your pants are
It really depends on what their colors are. Usually, a team will have a white uniform that has their team color as an accent for one uniform and their team colors will be on the other one. Or, they will wear one color on top and their other color on the bottom for home and then switch it for away. Like say the team's colors are orange and blue then they may wear blue on top and orange on bottom for home games and orange on top and blue on bottom for away games. Each team has different colors so they all have different colored jerseys.
