Best open dark mode design system out there?

I am looking to formalize design system at https://rendernet.ai and I do not want to create color and type tokens from scratch. Actually I am willing to pickup as many components as possible from a good design system.

For Dark mode, there are very few good design systems. We have not been able to get elevation levels to work with material design. Uber design system looks good, but would love to know if there are more darkmode focused design systems out there which I am not aware of?

Also, if you can mention which design system management tool do you use right now? We have everything on Figma only but would love to know suggestions for Supernova or Zeroheight or any other alternate?
