Re: I like the idea
High Viz? For sure, the workmen's jackets are a bright shade of orange... but so are the plastic road barriers and their 360 digger. *Everything* in their immediate environment is the same shade of orange. How can the digger driver see his mates if they are sodding *camouflaged*?!
Or maybe they're like zebras, they do it to confuse predators.
(Or whatever the latest thinking on zebra stripes is. I had heard it was to differentially heat air and thus create thermal currents for cooling. Or maybe it was to befuddle biting insects. )
