A property of quarks and gluons that determines their strong force interaction with each other (especially the attractive and repulsive forces between them). Color charge is considered to be a form of charge, much like electric charge. Although there are three basic color charges (designated blue, green, and red) along with associated anticolors, color charge has nothing to do with the more familiar notion of colors seen by the eye.
