  We review lattice studies of the color screening in the quark-gluon plasma.
We put the phenomena related to the color screening into the context of similar
aspects of other physical systems (electromagnetic plasma or cold nuclear
matter). We discuss the onset of the color screening and its signature and
significance in the QCD transition region, and elucidate at which temperature
and to which extent the weak-coupling picture based on hard thermal loop
expansion, potential nonrelativistic QCD, or dimensionally-reduced QCD
quantitatively captures the key properties of the color screening. We discuss
the different regimes pertaining to the color screening and thermal
dissociation of the static quarks in depth for various spatial correlation
functions that are studied on the lattice, and clarify the status of their
asymptotic screening masses. We finally discuss the screening correlation
functions of dynamical mesons with a wide range of flavor and spin content, and
how they conform with expectations for low- and high-temperature behavior.
