Iphone 6s rose gold color difference

I had bought Iphone 6s in feb 2016. I got some software issue. I got new phone today by the apple service centre. But there is a color difference between the two rose gold models. The one I got today is more of a peach color. Service centre person told me that apple has changed the color now.

This is really annoying. And nothing is mentioned on the website. I am really not happy with the new phone. I had specially bought 6s for rose gold color 😟
