I do know that food-aid packages had to change colour because they were the same yellow colour as bomblets dropped in cluster bombs, and these were killing children.
> General Richard Myers, the chairman of the Joint Chiefs of Staff, addressing the similarity between food aid packages and cluster bombs said, "It is unfortunate that the cluster bombs - the unexploded ones - are the same color as the food packets."
> "We have dropped flyers that show the pictures in the proper language explaining why you want to go to one and you don't want to go to the other. We hope that helps."
Hard to say. Studies like what color means to a people are really hard problems. It used to be in the Victorian age that red was manliness and blue was womanliness. That obviously switched for our culture.
I remember when I was younger the UN Dropped pink bottles of food to the Masai.
The Masai men didn't like the feminine implication and refused to consume.
Will be curious to know how this is marketed to the people.
