Default variables being used or ignored

I have a project setup like so (I'm using sass/scss):

`themes -> themefolder -> themepartials`

Inside the themes directory is a `_base_theme` file which contains all the `!default`'s for the themes. Inside the `themefolder` is a `_base` file which overrides the default colors.
Each partial theme file (ex: `_inputs`) displays the default colors, not the overridden colors from `_base` (which overrides the defaults).

Another issue I have is, I have a `$hue` variable which gets plugged into some hsl values, however the references to those values are not pulled into the partial theme files.

Here's an example:

```
$hue: 155;
$transient-light-trans: hsla($hue, 100%, 60%, 0);
$head-1-color: opacify($transient-light-trans, 0.97);
```

Now in the same file, the `$head-1-color` displays the green color perfectly, with the proper opacity.
If I use the `$transient-light-trans` color in a partial (with import) the color is not preserved and I get a gray transparent overlay.

I hope I'm just overlooking something.
