Xbox 360 and xbox one Controller for Windows real vs fake

[Wanted-x]

I have seen lots of Xbox 360 and Xbox one controller in market. Some are red colors some are green white combination. How i can identify which one is real and which one is fake??

I did not find any video about Xbox one controller which identifies the real vs fake.
 
I am eagerly waiting for help from support. Please provide real controller pictures with fully boxed if anyone can.

Both are real since the red packaging is the xbox360 controller for windows variant while the green and white packaging is the xbox360 console variant (nothing is different, just the packaging).
