Screaming yellow works

[goldfinch]

I can't remember where I read it, but high visibility chartreuse is supposed to be the most visible color. I see more and more highway workers wearing that color. High viz yellow is right up there, as is blaze orange.

I used to ride motorcycles and I had a blaze orange helmet. There was a substantial difference in how cars kept their distance from me when I wore that helmet. I've wondered why bike helmets don't come in high visibility colors.
