How do I switch to specific colorscheme style on the fly?

[gmnz]

Hi, so for example I have vim open with the "light" style and I want to switch to let's say "darker" or "warm". How do I do that? Not toggling but switching to specific style. It used to be possible to switch between light and dark by changing vim background from light do dark or vice versa, but that doesn't work anymore for some reason, so right now I'm using an older fork of your colorscheme where it still works: https://github.com/otakutyrant/onedark.nvim
