Well spotted Rodolphe, I skipped that video for some reason. I notice the same red flames as in the other clip but they appear clearer and longer since there was no external lighting this time. I agree that the engines are probably poorly set up in this case. So...blue flames when running efficiently and redder when the mixture is made richer.
I still see no reflections on the cowlings.
I've taken a few more stills to illustrate in the attached piccy.
