Can we add individual color variables to a "palette" that is shown combined?

At OddBird, our color-use is built around maps, but that's many teams prefer individual variables. I'm wondering, particularly with the move to sass-extract, if we can provide an annotation for adding colors to a palette?

// each color is added to the palette…

/// @palette brand-colors
$brand-blue: hsl(195, 52%, 31%);

/// @palette brand-colors
$brand-orange: hsl(24, 100%, 62%);

/// @palette brand-colors
$brand-pink: hsl(330, 100%, 45%);

// the palette is displayed and documented as a group
/// @colors brand-colors

@mirisuzanne Yes, something like this would be doable. I'll start by requiring @colors to be in a map, but if you confirm the API you'd like to use for this, we can add it.
