I'm gonna show you how to use the new Apple TV 4K tvOS 14.5 feature Color Balance to adjust colors on your projector. You're gonna need an iPhone with Face ID sensor (any newer iPhone like iPhone X or SE 2020 will do) and iOS 14.5+, Apple TV 4K 1st or 2nd generation with tvOS 14.5+ and a sheet of white paper to wrap the iPhone in.

I have not invented this technique, the credit goes to Tyler Loch:
