My wife has the iPad mini 4 with both the white Smart Cover and white Silicone Case on it and looks perfect! We absolutely love the look. It's clean, modern, and elegant looking. In fact the design is too perfect as the Smart Cover aligns all too well with the lip of the Silicone Case so you have to use the your finger nail to open it. But when closed, the seams almost all disappear.
Unfortunately I'm not at home at the moment to take a photo of it but I'll try to remember to do it later and post a picture up for you, unless someone beats me to it first.
And I mentioned this in another thread but I'm personally annoyed right now that Apple hasn't released a silicone case yet for my iPad Air 2 yet. I'm pretty jealous of my wife's case right now
