### Description

We study the transitions between the different color states of a static
quark-antiquark pair, singlet and octet, in a thermal medium. This
is done non-perturbatively exploiting the infinite mass limit of QCD. This study is interesting because it can be used
for future developments within the framework of Effective Field Theories
(EFTs) and because it can be combined with other techniques, like lattice
of quarkonium in a medium. We also study the obtained expressions
in the large $N_{c}$ limit. This allows us to learn lessons that are
useful to simplify phenomenological models of quarkonium in a plasma.
