Ruby with Dark mode

Hellow,
This is repost from github because the dev told me to post it here. I’m sorry if this is the wrong category (please, feel free to move it if it is).

Asking to Ruby theme dev:
Would it be possible to add dark mode to Ruby by default? I mean like in Casper, where it changes automatically. I think this would give a better experience for a lot of users!

Thank you!
Nick
