In all seriousness, why would you make something like this in olive drab? It serves no practical purpose that I am aware of to use that particular color.
Why not make it retroreflective orange or something, to ensure high visibility? If I were the person working on a bomb, I imagine I’d want my support staff to be able to see me clearly at all times - especially if the thing went off (but wasn’t powerful enough to just shred me to pieces) and I needed to be dug out of the resulting mess for medical treatment.
