Quarks and gluons interact so frequently that it makes little sense to regard each color state as a unique fundamental particle. These interactions also do not change any of the quarks' other properties. Correct?
For quark flavor, however, switching one for another also changes the mass. This is due to the Higgs mechanism. Two quarks in a doublet otherwise correspond to different weak charge states, similar to a color transformation in QCD. Strangeness and charmness represent the weak color in the 2nd generation, for example. Is this so?
Thank you for being patient with a physicist who is curious far beyond his own level of mastery!
