Question: Is it meaningful to think of the repulsion of mutual color charge and the attraction of three different color charge in QCD as being indicative of the classical concept of work taking place?

Exactly, how is this explained in the context of three charges needed to elicit the attraction, or in other words the attractive motion of three quarks?

Classical concepts are seldom useful in the quantum domain. Yes, you can stretch them to try and make things sort of fit together, but you really want to be using quantum mechanics.

If you think "red" and "anti-red" are physical things, you probably also misunderstand how color works.

If by the “classical concept of work” you mean the ##W## in ##W=Fd##, no. There's nothing analogous to the classical concepts of distance or force here, so no way of applying that classical definition of work.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
