Variables: Color alias with alpha / opacity (rgba ideally)

Just started to work with variables and I cant stop wondering what stopped Figma from implementing this from the beginning.

+1 for wanting to be able to manipulate alpha transparency independently on aliased color variables.

My immediate use case is for establishing state variants for various semantic application colors (e.g., disabled items are transparent) that still reference our core color primitives.

The goal is to be able to set transparency at the semantic color definition level (rather than manually at the layer level) without having to either unlink each color from its respective primitive or, alternatively, maintaining entirely separate primitive color scales for each potential transparency level of ever single color within our primitives collection.

Please add this feature!

+1 !!! I dont understand why this feature wasn’t implemented in the last update !

+1. Please make variables usable.

+1. Please take variables to it’s true potential!

Im replying so the thread doesnt close, but I want this too. Very badly.

Growing a design system at our company and missing this feature badly right now as we do not want to use workarounds or third party plugins for maintaining variables.

+1 to this please

Actually I’ve found that you can create a primitive token using a Hex and opacity, and then simply referencing this from other tokens (as I would other colour primitives) does the job.
