A recent leak from Macotakara reveals that the iPhone 7 may be introduced in a new color, Deep Blue.
This would in fact be a deeper color than the iPod touch 6th generation in blue. Rumor has it, this color will be replacing Space Gray, but this is very unlikely. Space Gray is a very monumental color to the iPhone, and for a lot of people, it would be sad to see it go. However, a "Jet Black" color option would be well suited for taking Space Gray's position. Jet Black would be an all blacked–out phone, like the iPhone 5.
