[Retros] Questions on Coloring Problems

[Kevin Begley]

@Andrey,

 I did encounter something around a handful of coloring problems using
all-black units.
 I can understand why journals printed them this way in the past -- lacking
neutral publishing options -- but, there's little reason to continue this
practice.

@Alain,

 Your methodology is only functional when all units are of an unknown color.
 You really should rethink the matter. :)

   Best,
    Kevin.
