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.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...
I am not sure if this falls under classical physics or quantum physics or somewhere else (so feel free to put it in the right section), but is there any micro state of the universe one can think of which if evolved under the current laws of nature, inevitably results in outcomes such as a table levitating? That example is just a random one I decided to choose but I'm really asking about any event that would seem like a "miracle" to the ordinary person (i.e. any event that doesn't seem to...
