I am using a dark theme and the latex previews from auctex are created with black text color. How can I change it? What I can do is change the background color to white (in Preview Reference Face customization), then I can at least read the text but it is irritating. Setting the foreground there did not work for me.
I also already tried to inject \color{white} into the latex commands somehow but without luck. Where would be the right place?
