Scss theming depends on body class with predefined variables

You can compile css files twice for each theme with different colors (and other editable things).

File with all "light" variables light-theme.scss:

$color: black;
$background: white;

File with all "dark" variables dark.scss:

$color: white;
$background: black;

File that contains all you styles _style.scss:

@import '_button.scss'; // If you are importing something
@import '_header.scss';

element{
  color: $color;
  background: $background;
}

And file where all themes are generated themes.scss:

.light {
  @import 'light-theme';
  @import '_styles';
}

.dark {
  @import 'dark-theme';
  @import '_styles';
}

Css output:

.dark element {
  color: white;
  background: black;
}

.light element {
  color: black;
  background: gray;
}
