How can I fix black screen during Google searches on iPhone?

Perhaps you have the Google browser set to Dark Theme. In the bottom of the screen is Settings. Click on it and select Search Settings > Other settings > Dark Theme to turn it OFF.

If you mean something else please elaborate.

While there is a google inversion tool ~ that, I've not consciously used.

In the Apple, macOS X: A path to invert black to white, & back, goes

something like this:

"Invert colors on your Mac? Go to System Preferences, select Accessibility, then Display,

and check the "Invert colors" option. You may also use Keyboard Shortcut, "Control +

Option + Command + 8" ~ to toggle the B&W inversion effect, on and off."

This was one of the first things an elementary school pupil did, with

a Mac, to get the attention of his/her instructor. Often took much of

a class period, to sort this mystery out. Way Back in the early daze!

(And much later than my first computer experiences, too.)
