Baryons always contain three quarks, and at any time may also contain some gluons (its the force that keeps the quarks together), and the quark-antiquark pairs.
All baryons have a neutral color when all the quarks are combined.
For each baryon, an antimatter baryon exists, composed of the 3 corresponding antiquarks.
The following table will show some basic baryons.
