El tema simple de Sam

[Alex_P]

Yeah, I am also interested in this, just asked a similar question here:

How to make a theme with different color palettes?

I installed this theme Sam's personal "minimal" topic list design, it uses light colors by default. I want to allow users to use it with dark colors. What is the best way to achieve this? Do I need to somehow install it two times and set different color palettes? Or there are better ways?
