dark mode on display

I'm on Ventura 13.4.1 using a Mac Mini M1. Recently when I went to Google using Safari, my display entered the "dark mode" and has remained there since, but only in Google This happened after installing a drum beats software package (ToolTrack Drummer 3).

In Safari, If I switch the homepage to something other than Google, the screen returns to normal.

To my knowledge, I am not running Google Chrome in

Any suggestions?
