Introduction to color charge

In particle physics, color charge is a property of quarks and gluons. Under the framework of quantum chromodynamics (QCD), it is related to the strong interaction between them. Color charge is analogous to the charge of a particle, but because of the mathematical complexity of QCD, there are many technical differences between color charge and charge. The "color" of quarks and gluons has nothing to do with visual colors, but is just a peculiar name for a property that hardly exceeds the size range of the atomic nucleus. The word "color" is simply because there are three types of color charge, analogous to the three primary colors; relatively, there is only one type of charge (but there are still positive and negative).
