Quarks have color just like particles that interact electromagnetically have charge. Color exchange via gluons is the way strong force is carried.
Secondly, the whole "6 quarks and 6 leptons" thing is just 3 generations of fermions. You have the up and down quarks, the electron, and the electron neutrino. The higher generation particles are a consequence of flavor dynamics due to the weak force.
Finally, there is much more to the Standard Model than the fermions you're describing. It's also the bosons, and the dynamics of how all these guys interact with each other.
