Color Blindness

Nope, I am not giving a lecture on Color-blindness. If you want to read about color-blindness, then this article is for you. All I want to tell is that Color-blinds don't see the world in B&W.

Our eyes are like the color computer monitors or color TV (Actually its the other way round, they took inspiration form human eye system). It has three nodes to give the entire spectrum of colors. You might have heard some where or the other about the RGB (Red, Green Blue) nodes. Thats what we have in our eyes too, which help us define the entire color spectrum.

The simplest way to explain color-blindness: Remember, when your color TV got old, one or the node stopped working so that you had a greenish hue or reddish hue over everything. There were certain colors that didn't appear right. Thats how color blind people see the world depending upon which color node is defective (I think. I am not an expert on the subject so thats the best I can come up with) . The most common ones are red and green blindness. Blue color node usually work for most people (only one in 10,000 people has blue cone/node defective). Anyway, here is how different color-blind people see the rainbow.
