I guess you are referring to the quark coor currents

[tex]j^a_f = \sum_{ik}\bar{\psi}^i_f \gamma^\mu (T^a)_{ik}\psi^k_f[/tex]

You get such a color current (where ik and a are the SU(3) color indices) for each flavour f. For the total color current you have to sum over all flavors f=1..6. Is it this what you mean?
