Change the background color of themes

[Mailiax]

Maybe I am just stupid, but I can't find a way to change the background colors of the dark and light themes.

Shouldn't you just be able to import pico in an scss file, change --background-color: in the mixin, and then compile it to css and import it into the project? This doesn't work for me. The resulting css file does not reflect the change of --background-color: in the scss file.

This works in custom css file

:root {
  background-color: red !important;
}

Obviously you can set it for light and dark themes.
