Arena hazards?

I thought I’d read that somewhere, thanks for clearing that up Alex.

Final question (probably) would it be better to use white lighting or colours? Already planning on a red glow for the pit areas, and was thinking of lighting in the corners a la Robot Wars, is plain white too boring?

Remember that too much 'blue' light causes effects in camera sensors and makes everything go violet in the picture.
