Visual Studio Code Theming - Change CSS Syntax Error Font Color

Question

In addition to this great Q&A, found at Visual Studio Code Theming - change editor error indicator, I am curious what setting / scope controls the font color during an error output in a CSS file? I'd like to be able to change the default value. Thank you in advance.

As you can see with the Developer: Inspect TM Scopes command, it doesn't really seem to have a specific "error scope", just the standard meta.selector.css that other selectors also have:

Depending on what you want to do, that might still be good enough. Selectors without an error appear to have an additional, more specific scope like entity.name.tag.css according to which they're colored. So if you change the color of meta.selector.css, other selectors are still colored differently (at least with the default theme):

"editor.tokenColorCustomizations": {
    "textMateRules": [
        {
            "scope": "meta.selector.css",
            "settings": {
                "foreground": "#fff"
            }
        }
    ]
}
