 - `order::Union{AbstractOrder,Tuple}`: the order in which the columns or rows are colored, which can impact the number of colors. Can also be a tuple of different orders to try out, from which the best order (the one with the lowest total number of colors) will be used.
 - `postprocessing::Bool`: whether or not the coloring will be refined by assigning the neutral color `0` to some vertices. This option does not affect row or column colorings.
-- `postprocessing_minimizes::Symbol`: either `:all_colors`, `:row_colors` or `:column_colors`. This option only applies to star and acyclic bicolorings.
+- `postprocessing_minimizes::Symbol`: which number of distinct colors is heuristically minimized by postprocessing, either `:all_colors`, `:row_colors` or `:column_colors`. This option only affects bidirectional colorings.
 - `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.
