I am using Pylance in VS Code (Dark Theme), writing Python 3.9. When semantic highlighting is enabled, well defined variables are colored in cyan and when I use a variable that is not defined (and will yield error when running the code) it is colored in white.

I want to change this such that a well defined variable will be colored in white and undefined variable will be colored in red (the color of error).

I know I need to edit the settings.json but I didn't find what I am looking for in the documentation below.

Updated test code:

# test
import numpy as np
import os.path as osp

def f(x):
    return 6*x

fx = f(x=1)
fbad = f(x=bad)

x = 1
y = 2   x   z

a, b = 1, 2

class test():

    def __init__(self):
        self.x1 = 1
        self.x2 = 2

ins1 = test()
print(ins1.x1)

The following configuration may be useful to you

// settings.json file
{
    "editor.tokenColorCustomizations":{
        "[Default Dark ]": {
            "textMateRules": [
                {
                    "scope": "meta.function-call.arguments.python, source.python",
                    "settings": {
                        "foreground": "#FF0000"
                    }
                },
                {
                    "scope": "variable.other.readwrite",
                    "settings": {
                        "foreground": "#ffffff"
                    }
                },
                {
                    "scope": "punctuation.separator.arguments.python, punctuation.section.function.begin.python,punctuation.separator.parameters.python",
                    "settings": {
                        "foreground": "#D4D4D4"
                    }
                },
            ]
        }
    },
    "editor.semanticHighlighting.enabled": true,
    "workbench.colorTheme": "Default Dark ",
}

looks like this on my computer

Note that the above configuration may cause other unexpected changes. Because scopes of changing the color might work in some other places as well.
