How to restore my ios9 from totally greyscale to full color?

[iMore Question]

Overnight I woke up to greyscale. I already had my phone set up in do not disturb (auto) from 10pm-7am. While looking for an answer I found info on "Nightshift" I did not install it but I found it and turned it OFF. Help please????

Welcome to iMore! Did you go to Settings > General > Accessibility > grayscale > Toggle off

As Led said, it's not Nightshift, that's something else, which you might actually want to keep on, it helps you get to sleep at night. It just makes your phone a little dimmer at night.
