Cvent Beginners

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).

I have run into this same problem myself. I have found the issue to be rooted in the theme settings, and what colors within your theme Cvent automatically maps to pop-up elements. I admit there's been a lot of trial and error, and I never seem to get the pop-ups to look 100% the way I'd like, but you may find this guide to be a helpful tool when setting your theme colors: https://support.cvent.com/s/communityarticle/Flex-s-Pop-Up-Modal-Colors?is_article=true&lang=en_US&searchFor=pop-up%20colors
