The complementarity, balance and symmetry (Ma'atian principles) represented in the Standard Model can be seen more clearly when we view all of the particles of the Standard Model Chart. For (almost) every particle, there exists a complementary particle with the same mass but opposite charge. The chart below highlights the various classes, charges, and "colors" of the particles.
Table showing the particles and antiparticle pairs of the Standard Model in accordance with their corresponding OSCI Modeling Systems.
