Gluon is messenger particles for the strong force between quarks. Its role is very similar to the exchange of photons in the electromagnetic force between two charged particles. The only difference is that Gluons themselves carry the color charge of the strong interaction. This is unlike the photon, which mediates the electromagnetic interaction but lacks an electric charge and unlike the single photon of QED there are eight independent types of gluon in QCD. In quantum chromodynamics (QCD), the theory of the strong force, gluons are vector gauge bosons that mediate strong interactions of quarks. The gluon has a spin of 1.
