As for me, old habits die hard. No matter that I know my red light is safe, I still keep an oversized sheet of beat-up black construction paper handy and will instinctively cover the exposed sheet of paper in the easel each time I step away for a moment. I just can't break that habit.

Actually, 7 minutes is plenty long for me. I used to do mostly color and as such was in total darkness. I usually us the safelight now if I can't work by feel, misplace something or get disoriented.
