I try to. I bought a Rose Gold iPad Pro to replace my Silver iPad Air 2 whilst my 6S Plus at the time was also Silver. I knew that when the iPhone 7 came out I would get it in Rose Gold. So now both my iPhone and iPad match. Unfortunately the MacBook Pro only comes in "Silver". As far as the Apple Watch goes I would have got it in Rose Gold if the Stainless Steel model was available in it but as I didn't want the Aluminium model my watch does not match.
