I've easily been able to change the color of the text in all the buttons on my registration form, but for the life of me, I cannot find how to change the text color of buttons in pop-ups, because they simply don't appear on any of the canvas pages. I've pasted the offending pop-up here and, as you can see "Yes" is all but invisible. These are our primary org colors, but I've changed text in all the accessible buttons to be black, for readability. None of the guidance I've found in the knowledgebase has addressed this specific issue. Any help would be appreciated (mostly by our future registrants, who might actually want to read what they're clicking).
