You mean colour blind.
Blind cannot see any thing but they can develop other senses and learn the tricks so that they can function well. They also can use various aids like Seeing Eye dog braille language, actually it is just the an English alpha bates, but they can read it by ruining their figures on the surface of the paper, in USA most signs have braille on it and they have standardise the height, they are proficient at using the cane to locate stuff with it by sound of the cane.
If your Q? was how the colour blind can drive a car and use signals that are Red, Green and Orange. By an international agreement, the international agreement dictates that they arranged in certain order, vertically and horizontally.
Next time if you see the traffic lights write down the sequence and compare it with the other, if they are not in same sequence call the people in charge to correct them at least on new installations. Make it your civic duty.
In USA they all are correctly installed.

There are two types of blind; one who is blind since he was born or from a very tender age and the other is accidental or deseased blind at a later stage of life.
Those who became blind since birth or early childhood cannot recognize colours. Because colours have no smell other than chemical, which is almost same for all colours. To them every colour is black.
But those who became blind at a later stage of line can imagine of a colour when they are about any specific colour.
Blind have muscle-memory for which they can recognize the voice, articles and even the road they are paving. But for colour it does not work. Had colour any particular shape, physiological element or any distinctive them they would associate it with the respective colour they told.

It appears a lot of blind people can sense a variation in heat source, so they do have a sense of intensity changes which is the colour world they live in.They also' feel' colour, as they make associations with texture and the word that goes with it, so when we say red, the colour will be stored as a feeling. So basically what visual sense we use to denote colour, they can convert it to another sense,like touch.

If you're BLIND, you can't SEE, therefore you CAN'T recognize COLORS.
