Terminology

Physicist Murray Gell-Mann coined the word quark in its present sense. It originally comes from the phrase "Three quarks for Muster Mark" in Finnegans Wake by James Joyce. On June 27, 1978, Gell-Mann wrote a private letter to the editor of the Oxford English Dictionary, in which he related that he had been influenced by Joyce's words: "The allusion to three quarks seemed perfect." (Originally, only three quarks had been discovered.)

The three kinds of charge in QCD (as opposed to one in quantum electrodynamics or QED) are usually referred to as " color charge " by loose analogy to the three kinds of color (red, green and blue) perceived by humans. Other than this nomenclature, the quantum parameter "color" is completely unrelated to the everyday, familiar phenomenon of color.

The force between quarks is known as the colour force (or color force) or strong interaction, and is responsible for the nuclear force.

Since the theory of electric charge is dubbed " electrodynamics ", the Greek word χρῶμα (chrōma, "color") is applied to the theory of color charge, "chromodynamics".
