This demonstration made me realize that I take my color vision for granted. There are so many different things that I have never thought about that require being able to see color. I always thought it would be inconvenient to be colorblind, but I never really considered how difficult it would make certain tasks.
I'm glad I m not color blindness. Of course, it is not like you are not being able to see, but not being able to recognize the colors must be pretty hard too in some situations. As it showed in those examples, for us, sees easy to see what meat is cooked, but it's hard to say to a color blindness person.
That was an interesting experience. I can't imagine going through my day not being able to see color. I would imagine someone who is color blind learns to deal with it and is able to complete tasks that everyone else does (like cooking meat). I knew someone in the military that was colorblind and they seemed to deal with it very well. From what they told me they learned to recognize shades of gray as different colors. I don't know how accurate they were but if it worked most of the time than I suppose it would be worth it.
I couldn't imagine going through life colorblind, especially when it is that severe! In class today we talked about how colorblindness is a sex-linked trait on the x chromsome and because men only have one x they are more likely to be colorblind than women. However, only the L cone and M cone genes are on the x chromosme. The S cone gene is not sex-linked and therefore very rare to have no S cones (tritanope). Someone without L cones is a protanope and someone without M cones is a deuteranope.
This was really interesting to me! I can't believe how much of a difference there is with people who are color blind. This makes me really appreciate my eyes as others have said above. We don't really imagine how many things we would miss with color blindness. As we discussed in class, it's usually the M and L cones that are affected with color blindness. Since this is a sex-linked trait, it mostly only occurs in men, since it would have to occur on both of the female's X chromosomes and only one of the male's. Since just the L cones and the M cones are on the X chromosome and the S cone is not, the L and M cones are the only ones affected. As stated above, a person without an M cone is a deuteranope, and a person without an L cone is called a protanope.
This is fascinating to me, but I know I'm not colorblind, but there are a couple one's I have to stare at for a bit until I can distinguish what the number(s) are inside the circles. I have a harder time seeing the number(s) when then the colors in the background are neutral and the number is a slight blueish gray.That is the only problem I have found, is that normal? or did anyone else find those more difficult to see the number right away compared to the others? As far as I know, no one in my family has it or is a carrier...
I have never thought about how many things I recognize due to color. I cook by color on a daily basis. You would have to have people with color vision with you while your out buying certain goods. I think it would make definately make life more challenging. I do not think that their are any carriers of colorblindness in my family. As we discussed in class men are more likely to have the trait as it is linked with the X chromosome. If you are without the S-cone you are considered a tritanope. A deuteranope is without M-cones and a protanope is someone without an L-cone.
