 Because of a phenomenon known as "color confinement", a hadron cannot have a net color charge; that is, the total color charge of a particle has to be zero ("white").A quark can have one of three "colors", dubbed "red", "green", and "blue"; while an antiquark may be
either anti-red, anti-green or anti-blue.For normal hadrons, a white color can thus be achieved in one of three ways
