Hello! I am a bit confused about the relation between the singlet configuration and symmetry of the system. So in the spin case, for 2, 1/2 particles, the singlet configuration is antisymmetric. But I read that the quarks are always in a singlet configuration, which means that they are symmetric in the color space. So as I understand, in one case singlet state is associated with symmetry, while in the other with antisymmetry. Is there a rule here? Thank you!
