The Live Polling text color is applied from the "Experience Design" Tool menu body text. This is inconvenient and confusing for the user since they think that the overlay message text color in the Overlay Response menu should also apply to the live polling text when it's enabled.
Since they need to change the Brand design color of body text > that means they have to manually change the text body color for each screen if it's different than the overlay live polling text color. Adding this video for additional context >
