Review layers - what design theme color do I need to change?

I am working on a long assessment for an internal credential, and trying to figure out how to get the review layers to work how I want them to. I want them to show the correct answers. However, when I have my review triggers set to do this, only the green checkmarks show up, but the actual correct answers that should be next to the green checkmarks are invisible.

I have messed with my theme colors and cannot for the life of me figure out what I need to change in order to actually be able to see the answers on review! Image attached to show what it looks like when trying to review, and how my color theme is set up.

The assessment is 75 questions, so it's getting really old and wasting a lot of my time to keep trying different methods, go through the 75 questions so that I can see the review layers, only for it to still not work.
