I got the Silver because I'm an OSU fan, so 1 color taken care of probably just get a red skin for it. I've already bought a clear case (I wanted a clear case to show off the phones beauty.)
I have a gold s6 now and I got over it pretty quickly, but i loved it at first. I went with a black S7 Edge because it looks awesome and this time it is actually black and not blueish black.
Silver! I originally ordered the black, but I changed my order after I saw the phones in the store. I love that shine andI'm a little tired of having a black phone.
Answers seem to depend on what color phones you had before. Silver seems popular because its a new exclusive color. I got Gold because i have a silver note 5. The Gold seems more refined this year and it will go with my watches. I will probably get an international black s7 edge if the rumors are true that there is no samsung logo up front. Pure jet black front yes.
