The eyes.
Mildly colour blind people can see the red/blue ends of the spectrum. However, they have great difficulty seeing the more subtle colours in the orange/yellow/green range.
If you can see '40 shades of green' , as in trees and grass etc., you are NOT colour blind.
Colour blind people are often banned from doing such work as ship/aircraft navigtion, train driving, driving large vehicles(traffic lights).
Color blindness affects the visual system, specifically the eyes and the brain's ability to process color information. It is typically caused by a genetic mutation that affects the cones in the retina, leading to difficulty distinguishing between certain colors.
Studies show that color blindness affects 8% of Caucasian men and only 0.5% of Caucasian women. Therefore, while the color deficiency is mostly a male dominated affliction, some women are also affected. It is believed that color-blindness comes from a gene on the X chromosome and thus would be part of life from birth. However, it has been discovered that color-blindness can occur with some diseases such as liver disease.

Not being able to see color in some cases. Mild color blindness might just be an inability to distinguish between colors like green and red. That is sometimes the case, not always. Did you know that 99% of all color blind people are not actually color blind, but color deficient? Does that help?
The cat's cry affects mostly the nervous system.

Dalton had requested that his eyes be examined after his death, in an attempt to discover the cause of his color blindness
It is found on the non homologous part of the X chromosome.
brain tumors affect whatever part of the brain they are in. If they are in the occipital lobe (the part of the brain that processes vision) they will affect the vision in multiple ways depending on where in the occipital lobe they are. I have heard of blindness, inability to see color (black and white vision), and many other peculiarities in vision due to tumors in the occipital lobe.
John Dalton donated his eyes to science when he died. He chose to donate his eyes because he believed that they were the most important for scientific study due to his work on color blindness and vision.
If your color blindness is genetic (as opposed to having been caused by trauma or neurological issues), the only part of the eye 'affected' would be the cones, that part of the eye responsible for discerning color.
Quite significantly as that body part is no longer there.
Every part of the body is vulnerable

Color blindness is not something that one can do to oneself intentionally. Colorblindness results from a defect within certain cells of the retina (part of the eyeball) or injury to the optic nerve, among other causes. Distortions in the cornea, the lens of the eyeball, (cataracts) also can cause partial color blindness.
