In reply to Shani:

The trouble is you can't see very far with red mode on most torches.
Modern Leds torches are so bight these days in close proximity shadows are less problematic and the ability to see much further means you can sometimes even avoid tricky ground altogether because you can plan a better line.
The latest petzl ACTIK CORE red lite is 2lm or at max brightness. The white light is 600 lm. Or at normal setting 100 lm. I'd rather work with the limitations of the white light than use the red light where I can't see anything more than my immediate surroundings.
