I installed the Human Prelight attachment. It behaves a little oddly for me: installing it adds another theme also called simply "Human", which looks different in the Appearance Preferences widget but doesn't change anything that I can tell when selected (see attached screenshot). I selected customize and manually set the 'Controls' and 'Window border' to "Human Prelight". That made everything very different from the human theme, although the toggle button works well and it's easy to tell whether the toggle is active or not even when the mouse is over it (see attached screenshot in next post).
