As the other reply said, in QCD you have "3 things that combine to nothing." If I had to guess why they are not so common I would say that the more variables you add in a theory the more complicated you make it. So by Occam's razor we try to go for the simpler models/structures.
- andyferris 3y agoOne line of thought here is that maybe there do exist larger, more complex symmetry groups that can broken to create more complex "charge" particles (e.g. electric charge < color < something else < ...), but that the masses of particles involved are so large, their lifetimes so short, etc, such that we'd never actually observe them (or at least, we can't yet observe them) and that the more complex the group, the less relevant the physics actually becomes. (Obviously I can't say whether that is true or not, but it might be a possible explanation of current observations).
