Came across this exert from the Mountain Safety Council "developing safe hunting practice" pdf......

No one colour is satisfactory as a protective factor for all conditions, however ‘United Nations’ blue
came out as the most visible colour in the greatest variety of conditions, but can be affected by going darker when wet
if made of an absorbent material. A range of high vis orange clothing was tested. It was good in most conditions, but
there are circumstances where it might be confused with deer, especially in some light conditions. The outcomes of this
project indicate that the wearing of colour that contrasts with the environment, on its own, is not sufficient.
Rather,
hunters need to modify a range of behaviours.
