When aliasing a color variable to another (img 1), or using it directly on an element (img 2), we should be able to override the opacity without the need to create a variable for each transparency variation:
+1 Just started using variables and while they’re great, it feels incomplete without this. Any solid color system needs to support defining variants relative to a base color.
+1 from me. Not having separation of transparency and colour variables is going to cause me lots of extra work, and will result in a messy design system that’s hard to manage.
