Are mesons color polarized?

The binding of quarks in mesons baffles me. It’s an Occam’s Razor thing.

Since a meson is a colorless, the simplest way to bind its two quarks together is to use a $U(1)$ Cartan subalgebra of $SU(3)$. That is, the two quarks would bind by exchanging only gluons whose color and anticolor components cancel out.

But if those were the only types of gluon exchanges occurring in a meson, then the color and anticolor of the two quarks in the meson would remain unchanged and persistent over time. That in turn would imply the existence of three orthogonal "varieties" or polarizations of meson, e.g. $roverline{r}$, $goverline{g}$, $boverline{b}$ and their compositions. There are more elegant ways to say that in group theory, but if you picture all the possible ways of orienting a symmetric stick in 3D space you’ve already captured the idea quite nicely.

By Occam’s Razor, nothing beyond Cartan subalgebra binding is needed to explain the existence of mesons. And if the time slice is small enough, I do not easily see how at least some degree of transient color polarization in mesons can be avoided, e.g. while they are "exchanging" a gluon.

So, by Occam’s razor there must exist experimental evidence in particle physics proving that mesons are not color polarized, or at least that they change their color polarization very quickly indeed.

So, three questions:

1. Does anyone know references or keywords for finding theoretical and experimental articles on meson color polarization, or why it does not exist?

2. If meson color polarization does exist, what studies have been done on the duration of color polarization in mesons?

3. If meson color polarization does exist, how are meson-to-meson interactions affected when mesons with similar or diverse color polarizations encounter each other?
