One can ask at this level,why there is no other observed particles made of another combination of the quark?qq or qqqq or even q for exemple? It’s because the existence of another degree of freedom for the quarks, called the color. More specifically,each type of quark is assumed to come in three different colors wich form a triplet under a color SU(3) group. The colors are R Red, B Blue, G Green..and it’s evident for every physicist that there is not a relationship between these hidden degree of freedom and the natural colors of lioht Il not a relationship between these hidden degree of freedom and the natural colors of
