Definition of color charge
: color 16 QCD predicts that quarks carry a “color charge,” mimicking the familiar electrical charge, which is the source of the force binding them together and is carried by gluons, force particles analogous to the photons of electromagnetism. — Andrew Watson, Science, 22 Jan. 1999 A blue quark will bind with a red quark and a yellow quark, forming a “white” object that has no color charge. The result may be a proton, a neutron or any one of innumerable three-quark composites called baryons. (Physicists call these charges “color” because all three of them add up to zero, just as the three primary colors add up to white.) — Frank E. Close et al., Scientific American, November 1998
