Comment (by jmantysalo):

 Relating to this: Where is default pink color defined? For example

 {{{
 G=DiGraph({0:[1]})
 G.show(vertex_colors='pink')
 G.show(vertex_colors={'#ff00ff':[0]})
 }}}

 shows kind of a bug: color of element 1 changes from pink to blue when
 setting color of 0 to red.

 Examples to `show()` could be something like

 {{{
 P.show(vertex_colors={'red':P.maximal_elements()})
 }}}

 or

 {{{
 for c in P.maximal_chains():
     P.show(vertex_colors={'red':c})
 }}}

 Where P would be suitable poset.
