Display while recording or not recording

Recently I went to a board meeting, of which I’m the secretary, which lasted for 2.5 hours. My phone was in the center of the room on a table which I could see from A distance. The phone was inadvertently moved while recording and it paused. The display colors, a bright red were easily seen from my position , but it being paused was not easily discernible. Unfortunately, I only got the first 30 minutes of the meeting. I would like to suggest that the screen color automatically change to dark blue if the program is not recording. I would have then been able to see that it had stopped recording and could have remedied the situation.
