Screen Recording - Changing the color of the highlight rectangle

I have been reviewing other threads and  can't seem to find what I am looking for. I need to know if I can change the color of the the rectangle that is inserted during a screen recording selecting a button or entering data during the recording. I would really like to change the border to a more visible color.

Near as I can tell changing the Theme colors has no impact on this rectangle. Any ideas?

Thanks

Roy
