So one day I was playing Pokemon X and I decided to Wonder Trade all the Axew's I bred looking for a shiny. After one particular trade, I had gotten a Nincada from Japan. Something looked a little off about it though: it had blue wings instead of the usual green. At first I got really excited because I thought it was a shiny, but when I looked it up, I found it that it wasn't a shiny.
I've tried looking everywhere for some explanation as to why my Nincada has blue wings but nothing. I haven't even found it to be the same situation with Vivillion and it's different wing patterns depending on where it was caught (Mexico, Japan, Korea, etc..) This has been bothering me for months. Can someone possibly explain it? I'd really appreciate it.
