Hope to adapt to dark mode

The anki-tex-as-image works well in normal mode. However, when I set anki to dark mode, the rendered formula is black on a white background, which doesn't look very harmonious.

I see the problem. I never use dark mode so have never thought about testing it. Probably easy to fix with css when I'll have some free time.

I am expecting a function like this. 😀
