Why are the colors that I've set in waybar transparent?

Hi, ever since I've switched to using Stylix, everything mostly works the same except waybar. All the colors I've set in style.css aren't being used at all and they are just transparent.

Here's the configuration in Home Manager:

stylix = {
   targets = {
      waybar = {
          enable = false;
          addCss = true;
      };

      # ...
    };
};

Also, I've set the opacity of everything to 1.0:

opacity = {
    applications = 1.0;
    terminal = 1.0;
    popups = 1.0;
    desktop = 1.0;
};

This is what it currently looks like:

I've already found the solution, I just had to redefine all of the colors in style.css
