After I saw this photo below and video unboxing from DroidLife, I already made my choice...
But for people who picked black onyx, don't regret it. The advantages are -
+ Black is easier for video watching
+ Easier to theme + OLED for floating effect
+ Easier to take photos in any lighting condition, front or back
For me, the only reason I want (although not need) an S7 edge is DESIGN. And I find the black to be the LEAST attractive. Even the white looks better to me. Silver isn't as garish as gold while still maintaining the aesthetics. Black covers up all the interesting design lines like it did to the One M7. From a distance, you put it next to a regular S7 and most people couldn't distinguish between the edge variant except size.
I also realized I have alot of video downloads but I actually prefer watching them on my TV or iPad. Only on occasion, I will watch a favorite video or stream on YouTube to kill time. I really don't like watching videos on my smartphone as I tend to get sleepy. I'm also not much of a shutterbug. So platinum silver wins for me but I wouldn't blame anyone for picking up any of the other excellent color options including the least reflective black for watching videos and taking photos which won't distract your eyes like the others.
