Colour Charge

The charge associated with strong interactions.

Quarks and gluons carry nonzero colour charges.

Quarks and gluons have colour charge and consequently participate in strong interactions. Leptons, photons and W and Z bosons do not have colour charge and therefore do not participate in strong interactions.
