iPhone 6s Rose Gold Color more like peach color

Hi

I have bought a new iPhone 6s Rose Gold 32 GB from Online Retailer.

I see the phone i received is not the usual rose gold color. Its faded out and looks like a peach color.

I contacted the retailer for replacement he mentions that the phone we delivered is rose gold.

And I checked with apple helpline they mentioned that the phone is not refurbished and its genuine. For change of product they said to contact retailer. But now as retailer has rejected the replacement order I have no choice left. I bought the iPhone 6s specifically for the Rose Gold color.
