Yesterday, February 27, was officially “Pokémon Day.” A celebration that has been going on for years now, it’s not a national holiday or anything (…yet), but it is a nice way for fans of the Pokémon franchise to commemorate their love for the series. Nintendo is obviously really big on Pokémon considering it has become the biggest multimedia franchise in history, so it wanted to celebrate this day with a fun event in New York City. So what better way to end the day than lighting up the Empire State Building blue and yellow.

I’m not quite sure how blue and yellow represent Pokémon, in particular, but some people have noted this could be a reference to the Kalos region. Considering the recently announced Pokémon Legends Z-A will be heading back to the Kalos region, maybe Nintendo is getting some subliminal marketing in before going full out with its PR push.
