General Science / Why Are Red And Yellow Most Visible?
« on: 25/07/2024 09:47:17 »
There is a story in the US. Fire engines are painted red so that they are more visible from a distance. Taxicabs are painted yellow for the same reason.
Why are red and yellow the most visible, or catchy to the eye, from a distance? Red and yellow have the lowest wave length on the visible spectrum. Is this something to do with optics and physics? Or is it just the human brain, maybe human psychology even?
Violet is at the other end of the spectrum. Shouldn't it be the most visible?
