`nullptr`?

This will result in a null deference in the pressed state.

Got to rename / remove this soon? Just as soon as we rename "modern-media-controls" right?

Please make sure this has a bug.

Using DisplayP3 for these seem unnecessary (especially for the one that can use Color::transparentBlack), but you do you.

Aditya and I are talking about that; we think both the setting and the ifdef can just go away now.

Yep, will file a few.

True, I was just typing them all straight from a color picker from a P3-space document.
