How to change slider color?

I am using the dark theme of jupyterlab. I am trying to get all colors inverted, but I am struggling with my sliders. How can I make them black?

This code does not impact the color of the right side of the slider. Only the left side.

pnw.IntSlider(start=0, end=10, bar_color='green')

I have also tried css theming, but i can’t find the corresponding css setting.
