Color, you ignorant limey.

So why isn't red, yellow, etc as easy to see?Â* If you wear a bright red

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.
