My guess is you have two options:

1. Customize the colors in minted to match what is on your screen. I am pretty sure that code in html looks very much like what is on your screen. This might be an entry point to customizing minted style. https://tex.stackexchange.com/questions/131456/customize-comment-color-in-minted-style

2. Customize the faces emacs uses for syntax highlighting to match the look in minted.

either way, I don't see a simple way to have a common theme between them, and they will probably always have some minor differences. It might be easier to hack a new exporter for src blocks that turns the htmlized code into latex markup perhaps.

I don't know how to do this and I guess it's difficult.

If you find a solution, please mention it here, others may be
interested.

Thanks!
