View Full Version : Can a specific version of color charge be detected?

A proton consists of 3 quarks; 1 downquark and 2 upquarks. These quarks have different color charges making the whole triplet color neutral, as nature requires.
Is it possible experimentally to tell a proton with a "red" downquark from one with a "green" downquark?

To my knowledge, the answer is no. The color designations are arbitrary, and you could swap red and green without changing any observable interactions.

Also as gluons carry colour charge and are continually being exchanged it is pretty hard to assign a static colour charge to an individual quark in a bound system. It is constantly in a state of flux.
