So what's up with all the Red, Blue and Green stuff and gen I references in this generation?
>Yveltal is red, Xerneas is blue and Zygarde is green
>Santalune Forest is same layout as Viridian Forest
>Bird Trio and Mewtwo are catchable in game in XY
>Snorlax at bridge
>gen I starters for free in XY and Mega evolutions for them
>Blue visited Kalos
>Origins
>Ruby and Sapphire remakes with Delta Episode and respective weather trio
>puni chan is red and blue, maybe a green
>anime logo is red, blue, green
>Zygarde Complete features Red, Blue and Green colouring
>RBY (And Green in Japan) coming to the VC
>the spikes in pic related are Red, Blue and Green

I'm not one of those people that shout KANTO CONFIRMED or anything, but it makes you think why there are so many references and usage of the colour schemes
