Text color of Dialog title is not getting changed

[sahillikeminds]

I was trying to change the survey color and after changing that my app starts showing the survey dialog with correct color but as soon user submit the survey and move to Thank you page, it shows Blue colored title named 'EDIT SCORE' which looks really weird. Also, there are no methods provided to change that text color. Please if someone could look into this, it would be great help.
