 - `postprocessing::Bool`: whether or not the coloring will be refined by assigning the neutral color `0` to some vertices.
 - `decompression::Symbol`: either `:direct` or `:substitution`. Usually `:substitution` leads to fewer colors, at the cost of a more expensive coloring (and decompression). When `:substitution` is not applicable, it falls back on `:direct` decompression.
