Review Quiz Slide Master

Hello everyone.

I added a Review Quiz button to my Results slide. When I previewed the assessment, the banner at the bottom of each review slide was light blue with white text, which was hard to read (see attached image). I looked all over the Slide Master and Review Master options and didn't see a master slide with a banner that looks like that. I can't figure out where to update the banner colors. Under the Design menu, the color scheme I'm using doesn't include that color, so I have no idea where it may be feeding from. Can anyone tell me where to go to change this?
