Quick Summary

In physics, "color charge" is a property of subatomic particles called quarks, analogous to electric charge. This charge is the source of the strong force that binds quarks together. The theory describing this is called quantum chromodynamics (QCD).12

Quarks carry three types of color charge: red, green, and blue. These charges combine to form "white" or color-neutral objects, such as protons and neutrons. The force particles that mediate the strong force between quarks are called gluons. Unlike photons in electromagnetism, gluons also carry color charge, which causes them to interact with each other. This interaction confines quarks within particles, meaning they are not observed in isolation.32
