Dynamic Data used in Styles

Just an idea, I’ve seen it mentioned over three years ago but it’s still not been implemented :frowning:

I think it’d be so useful to be able to add dynamic data into styles, a prime example for myself would be using colours.

In a button, I can do this: image

Yet when it comes to styles, I can only use a manual hex or colour picker.

Just a thought, what do you guys think about this?
