Hi @GeekSquirrel,

Thanks for the suggestion! We already have an enhancement in our backlog to explore this option though it hasn't been prioritized yet, you can find the details here: https://tree.taiga.io/project/penpot/issue/4135

@madalenapmelo-kp Thanks for your reply.
I have checked the previous issue #1486. It seems that solution is focused on “color group”, like creating alias for “color group”. But my solution is focused on "color". I think my solution could be more generic and be more consistency with var() function in css. Maybe you can make mention of this issue in that Taiga issue. So this could be a potential solution for you to reference.
