what is your iPhone model and what Software Version are you running?
Settings > General > About
Check Settings > Accessibility > Display & Text Size and check if any of the switches are on for Smart Invert, Classic Invert or Color Filters
Also, if this happens in the morning and at night.. Check Settings > Display & Brightness, is the switch turned on for Automatically changing from Light to Dark mode? You can toggle back and forth between the 2 modes here and see if this is what you are seeing. If you don't like your phone switching between these, just turn off the Automatic toggle switch
