A normal person might see Red and say, hey thats Red
A color blind person might see a totally different color but as long as they call it Red just like they were taught, who would know ?

Years ago I was a passenger in a friend's car at night, going down a long straight hill lit by orange sodium street lights. These just appeared as a stack of lights stretching out in two lines in front but halfway down were traffic lights on red. I thought he was leaving the braking late until we went straight through the reds without slowing at all.
Turned out he was red/green colour blind and normally read a red light by it's position in the trafic light. As this one just appeared as if it was another street light in a stack he missed it. Left an indellible print on my memory though
