I downloaded and installed your test deck. The images also appear just fine for me in dark mode. I am using a M1 Mac Mini, macOS Tahoe 26.3.1(a), Anki 25.09.2.
You might want to try Troubleshooting Step #6, trying different video drivers, to see if there is a video driver setting that produces better behavior for you. (Remember to fully quit and restart Anki after every video driver change.)
Also, (assuming you use AnkiWeb) does the problem behavior occur when you look at your cards on ankiweb.net using a web browser on your desktop computer? (Iām trying to figure out, āis the problem with the desktop computer itself, or just in the Anki appā?)
Itās in light mode, despite the browser being in dark mode.
Ah, I had forgotten that the ankiweb.net site doesnāt have dark mode.
Iām still interested in knowing whether the behavior might be affected by switching video drivers.
Well I just pulled up the troubleshooting deck myself andā¦it looks fine.
Does it look correct in the troubleshooting deck you made, but still incorrect in your study deck?
The only unusual thing I see in your āPictureā field is that youāve got an unnecessary anchor in there that turns the image into a link. Since the image is already downloaded and attached to your collection, that isnāt necessary. But I canāt think of a reason that would cause the image to invert.
For instance in this field ā

You only need this part ā
