Rainbow effect

It's light refraction from the unicorn tears.

 

It happens if your screen protector goes exactly to the edge of the lit up part of the front glass.

 

Sorry. It was a reference to one of the ingredients in the iPhone's construction being unicorn tears.

 

Take the zag off and see if it still does it.

Zag might have changed their design but I am betting it will go away if you remove the protector.

 

I think I know what your referring to. If the light refracts of the screen on a certain angle, it gives the spectrum of a rainbow when the screen is also completely clean. There is nothing wrong with your device.

 

Strange. But I truly don't think there is anything wrong with your iPhone display. His screen shows different colors and hues than yours does. Perhaps no two screens are alike.

 

Yes, iPhones do use unicorn tears for screen construction. It's why they're so strong and expensive.

Did you take off the phone's protective film before applying the protector and using the phone?

 

And the unicorn is crying because the graphic interface changed with iOS 7.

Corning calls it Gorilla Glass. I suppose that's because the gorillas are making the unicorns cry?

 

No. The Unicorns cry for Harambe.

 

Ok, good. (I assume nothing in MRF).

Probably just the finish of the protector. It's not unheard of and probably "within spec." If it is too bothersome, however, contact Zagg for a warranty issue. Their customer service and warranty are typically top notch.
