How to apply dark mode code block syntax colors to light mode

Things I have tried

What I’m trying to do

I would like to use a black background for code blocks in the light mode. Because I like how that looks in articles and tutorials. I figured out how to change the code block background color to black, so that’s good.

However the default syntax colors need to be changed because the light mode defaults don’t work on a black background. I need to change the code block syntax colors to the default dark mode colors, and I don’t know how to do that… can anyone point me in the right direction?
