The World Through A Colorblind Person's Eyes

What is colorblindness?

It's not always black and white, colorblind people can see colors but they just can't differentiate between certain colors. In fact only the most rare type of color blindness is black and white. The most common type of colorblindness is red-green colorblindness, this is where people mix up the red and green colors hence the name. Most people inherit the condition from their mother because colorblindness is an X linked trait.
The retina of the eye has 2 types of light sensitive cells called rods and cones. Rods work in low light conditions (like nighttime) and cones work in daylight specifically to differentiate colors. The cone cell also has three types; Each type of cone cell perceives each primary color. Colorblindness is usually caused by a fault in the cone and/or the pathway from the cone to the brain.

For example, playing "I Spy" with someone might be a little difficult (I discovered this early on with my younger brother). Christmas colors would look like a mixture of yellowish-green and color coordination your outfits in the morning in the morning would be a nightmare, good thing my brother has me.
