Default Why is hi-vis clothing easier to see? What’s so special about the colour?

Color, you ignorant limey.


So why isn't red, yellow, etc as easy to see?Â* If you wear a bright
red tshirt, you aren't as visible as wearing a hi-vis jacket.Â* Does it
convert all the wavelengths into one or something?


It's fluorescent. It converts ultraviolet (especially prevalent in the
dusk) into visible light. Presumably mainly available in certain colours.

Some, intended to be used at night, have strips that include glass or
plastic beads that reflect light (from torches or car headlamps) back in
the direction the light source is.

On a rainy day it's hard for drivers to see pedestrians and cyclists so
it's a good idea to wear or carry something fluorescent. ... Many people
don't realise it but… fluorescent colours don't show up in the dark or
'glow in the dark'. To be seen by drivers at night you need something
reflective.
