> You could achieve essentially the same thing with one main theme (that would contain all the shared styles) and 4 user-selectable color schemes. You would need to move all color calculations in the `color_definitions.scss` file of the main theme, but it is doable, I’ll try to find some time and give this a shot tomorrow.

That would be ideal, but I arrived at the current setup because multiple color schemes wouldn’t work for me. Some color schemes produce poor colors for auto-generated variables like `--primary-low`. Simply redefining the variable may work for one color scheme, but not another. A more general solution is possible if we redefine it based off `$primary`, or conditionally based on color scheme id/name, but without either multiple themes is necessary, so I can have a per-theme color\_definitions.scss (the duplication I’d like to avoid). Or is there a better option I’m missing?
