In the popup that appears when you click the identity box, the field data labels are the same colour as the background, so are invisible. The field data itself is visible, but I could not see any way to change the colour of the labels. Where is that set up?

What are #identity-popup-container, and .identity-popup-label in a theme? They do not seem to affect the background or the text colour of the field labels in the identity popup box.

If I am not mistaken, .identity-popup-label changes only the color of the ones highlighted in red, .identity-popup-description only changes the color of the ones highlighted in blue, #identity-popup-content-box changes the color of the ones highlighted in black, and lastly, #identity-popup-container changes the color of the whole popup (highlighted in pink).
You may also want to check if the selector of the parent object defines a color property (you can use DOM Inspector for this, I think).

I can confirm that DOM Inspector is super helpful. I use it in combination with Element Inspector. In the right panel, you can use the dropdown to see CSS rules of the selected element (and where they come from, and if they're !important), and you can even Ctrl+F to search for elements by ID, tag type, or non-ID attribute.

I cannot select anything in the identity popup. It disappears as soon as the main window loses focus. In order to select anything for DOM Inspector, I have to click the button in the upper left corner of its window. When I go back to the main browser window, I have to click the identity box in the urlbar again, and that is what is selected for examination in DOM Inspector.
With the Inspector in Devtools, it displays elements in content, not interface.

With Element Inspector, you should be able to open the identity popup, shift+right-click on an element, and see its properties. As you say, when the window loses focus, the popup disappears, but you can still see the elements in the DOM Inspector window, and with a screenshot reference or something, you can probably work out what's what. Or, you could take FranklinDM's word on what everything is. I hope this helps!

Okay, I finally managed to fix the problem I was having. I had changed the version number of the theme I am working on, and for some reason the older version was still installed and was interfering. Thanks for all the suggestions. Element Inspector works like a charm.
