Facially-constrained colorings of plane graphs: A survey

In this survey the following types of colorings of plane graphs are discussed, both in their vertex and edge versions: facially proper coloring, rainbow coloring, antirainbow coloring, loose coloring, polychromatic coloring, $?$-facial coloring, nonrepetitive coloring, odd coloring, unique-maximum coloring, WORM coloring, ranking coloring and packing coloring.In the last section of this paper we show that using the language of words these different types of colorings can be formulated in a more general unified setting.
