he three color types play a role in the process of hadronization, which is the process of hadron formation out of quarks and gluons. The result of two attracting quarks that form a stable quark–antiquark pair will be color neutrality: a quark with ξ color charge plus an antiquark of −ξ color charge will result in a color charge of 0—or "white" color—and in the formation of a meson. Analogous to the additive color model, the combination of all three color charges will similarly result in a "white" color charge. This is what happens when quarks combine to form a baryon.

The building blocks of the atomic nucleus—the proton and the neutron—are baryons. There are a great number of known hadrons, and most of them are differentiated by their quark content and the properties that these constituent quarks confer upon them. The existence of hadrons with more valence quarks, called exotic hadrons, such as the tetraquarks (qqqq) and pentaquarks (qqqqq) has been postulated.and several experiments have been claimed to reveal the existence of tetraquarks and pentaquarks in the early 2000s, but all the reported pentaquarks candidates have been established as being non-existent since. The status of tetraquarks is still a matter of debate.
