CSS help - unmade page color?

Hi all! New to CSS and had a quick question.
I was wondering how to change the color of an unmade page in obsidian? As of now, it just dims (shown below) but I know some themes like Blue Topaz are able to change the color to something else. I’d appreciate any help!

The css class for “unmade” notes is is-unresolved so if you want to customize the color/display, you could add something like:

a.internal-link.is-unresolved {
  background: yellow;

And you’d get:

You could then put that in a snippet.
