This is not in the quiz itself. It is in the Player. It is the "Quiz Navigation Warning Message" and "Quiz Navigation Titles." This color is not user adjustable within the PPTX. This message appears when the user tries to navigate past an incomplete quiz using the Player control forward arrow (hitting "submit" while incomplete works fine because that is a modifiable message box within quiz in the PPTX). The Player appears to be reading the background theme color (which is light to contrast against dark text) applying it to its text warning that appears against a light grey pop-up alert box (a box that is not modifieable within the PPTX). My guess is this is something that has to be re-coded in a configuration file.
My suspicion is it has something to do with this in the file "vconfig.xml" -
<uitext name="WARNINGMSG_TITLESTRING" value="Quiz Navigation Warning"/>
<uitext name="WARNINGMSG_MSGSTRING" value="There are un-attempted questions in this Quiz.
Clicking Yes will take you out of the Quiz. Click No to continue the Quiz."/>
The text of the incomplete quiz warning message is not customizable as of now.
Instead of changing the text color , you can chage the theme color to make the text readable .
Please follow the steps to chage the the color.
1. Open your presentation.
2. Go to AdobePresenter>> theme. Theme Dialog will open.
3. Chage the theme color in the bottom left hand side.
4. Publish presentation.
I hope this will help you.
