Your usecase seems covered by https://drafts.csswg.org/css-color-5/#relative-colors

> For example, if a theme color is specified as opaque, but in a particular instance you need it to be partially transparent:
> ```css
> html { --bg-color: blue; }
> .overlay {
>   background: rgb(from var(--bg-color) r g b / 80%);
> }
> ```
> In this example, the r, g, and b channels of the [origin color](https://drafts.csswg.org/css-color-5/#origin-color) are unchanged, indicated by specifying them with the keywords drawing their values from the origin color, but the opacity is set to 80% to make it slightly transparent, regardless of what the origin color’s opacity was.
