View Here : All Black Wallpaper
This wallpaper makes jet black Dock and folders. Probably, it works on all the iOS 10 device. So suited to the new color iPhone 7 Jet Black (or Black)!
Why Black? The reason is simple I love to have black colored desktop, it makes the desktop more attractive and over everything else black color is always gentle to the eyes. Maybe you would like to have these wallpapers on your desktop.
