There are 3 polarities of color charge: R, G, and B. In contrast, electric and magnetic charges both have only 2 polarities, respectively, positive (+) and negative (-), and north (N) and south (S). However, the latter cannot be isolated into a single monopole of either N or S pole. Furthermore, the single polarity of gravitational charge, the graviton, also defies continued experimental detection.

In terms of global gauge invariance, the color charge presents a more complicated system configuration. If the entire universe is made up of 1R, 1G, and 1B then the net color charge is zero and the universe is colorless. Adding equal amount of R, G, and B preserved the global gauge invariance symmetry of color charges. Fortunately, this complex color charge gauge invariance extended deeper into the atomic system and remained at the domain of the hadrons: baryons and mesons. It exclusively applies to the quarks and gluons. Although local gauge invariance symmetry of color charge need not be conserved as required by the principle of asymptotic freedom and Yang-Mills gauge field theory the 8 directional invariance properties of gluons enforced the domain of infrared slavery to few multiples of the Planck length. Since gluons are massless their fractal dimension should have been ½ or 0 but assuming their spin is 1/3 would make their fractal dimension equal to 1/6.
