@una Ah so you want it to be inherited somehow? That's not what I would expect for the name of `currentBackgroundColor`, and there comes more complexity...

Firstly, all elements have background color even if you do not specify. It's `transparent`. Are you proposing that we simply ignore that specific value? Or are you proposing we only use the background color if there is a cascaded value? Either way that would work differently from what `currentcolor` does... likely in a worse way.

For your specific example, actually, `button` usually comes with a default background, are you proposing some mechanism to ignore non-author rules maybe?
