I define a color palette in a _palette.scss file:

$color-0: white;

and then I @use is from another file:

@use "palette";

$font-color: palette.$color-0;

I've tried as well to use an explicit namespace @use palette as palette or to put everything in the global namespace @use palette as * but I get the same error message:

Undefined variable: "$color-0"

Yes, @use / modules is a relatively new addition to sass, and is still not supported by any implementation other than dart sass. You don't get an error message for the @use line itself, as it could be a general @-rule that should be preserved to the css.

Status of module support in rsass:

Release 0.16.0 - 2010-11-10
e2a2f0c 
Progress: 2718 of 5840 tests passed in dart-sass compatiblilty mode.

### Breaking changes

* `SourceName` and `sass::Item::Import` was changed by #62.
* `Use` was added to the `sass::Item` enum by #80.
* Changes to `sass::Value` and `css::Vaue` by #81.

### Improvements

* PR #80: Implement `@use` for standard sass modules.  All standard
  modules are at least partially supported, only `sass:string` is
  fully supported.  See issue #60 for for module support status.
* PR 82: Implement hwb support in `sass:color`.
  Also, provide `From<Rgba>` for `css::Value` and deprecate color
  value constructors.
* Provide `From<bool>` for `css::Value` (and deprecate `Value::bool(v)`).
* PR #62: Improve `ParseError`, `SourcePos`, and `SourceName` by using
  located spans by [nom_locate](https://lib.rs/crates/nom_locate) in
  the parser.  A `sass::Item::Import` now handles where each file is
  imported from, to improve error reporting.
* PR #81: Improved number handlig.  Now `Value::Number` handles both
  machine-sized rationals, bignum rationals and floats internally and
  `Value::NumberBig` is removed.  Also, `Value` no longer implemnts
  `Ord` but only `PartialOrd`, to handle f64 NaN an infinite values
  correctly.
* Improve parsing of `@else` clauses.
* Update spec to 2020-10-29.

I'll close this issue now. @use is mainly supported, and there are separate issues for the pieces remaining.
