White versus Black and reversed

Someone has probabaly proposed this before but are we seeing an alt reality on the island as well?  Dogen, The hippie, just new characters in general.  The Lost Logo is always Black with white lettering except when Jughead is/isnt detonated after that it is reversed.  This would explain the lighthouse, the other “others”, and some many added questions this season.  Did the writers send us a big clue or is this just another red herring?
