color charge

Meaning

Noun

• In the Standard Model of particle physics, a property possessed by quarks, antiquarks, and gluons that determine rules for how these particles may interact. There are three pairs of colors and anticolors: red, green, blue, and their corresponding anti-colors (e.g. anti-red).

Origin

• From a loose analogy to the set of primary colors. The charge property has nothing to do with visible color.
