RED!
Some names for specific types of raised pavement markers include Botts' dots, delineators, cat's eyes, road studs, or road turtles. Sometimes they are simply referred to as reflectors.
The average road reflectors in America are orange. Orange is the standard color b/c it is bright and can be highly reflective. Also, the color orange usually stands out on roads.
Catseye's are reflectors that sit in the middle of the road and light up at night.
Because the light from the head lights reflect off of them giving the driver a glowing object and a clear view of what's around them. Usually glass beads or reflectors containing prisms. By a combination of refraction, reflection and refractive index. The light enters the reflector, gets bent and hits the internal wall. The refactive index causes total internal reflection, it then exits back the way it came.
