Colors
This week I was wondering about colorblindness. I have some friends that are colorblind and have always wondered what exactly they see. Is it all black and grey or is it just not as vibrant of colors.
So, I did some research and, of course, it is commonly known that colorblindness is genetically linked to the X chromosome, but what I didn't know was that there are several types of colorblindness. Besides complete colorblindness, there is red-green colorblindness and blue-yellow colorblindness. Diagnosis of red-green colorblindness can be determined by the Ishihara color test plate. This test consists of a number of colored plates, called Ishihara plates, each of which contains a circle of dots appearing randomized in color and size. When colorblind people are presented with this test, they see the number 21 instead of the number 71. The numbers 7 and 1 are colored in green while the remaining picture is red. However, if presented to someone who is completely colorblind, they will see nothing at all.
Red-green colorblindness is the most common kind of colorblindness, and unfortunately it is not curable at this time. However, there has been some special creations to help people with colorblindness see more. Special lenses that have been created may help people with red–green color blindness when under bright conditions. There are also mobile apps that can help people identify colors.
People who suffer from colorblindness are ineligible for some jobs and many find this to be controversial. I can understand from a safety stand point how they may be unfit for certain jobs, but if technology keeps advancing at today's rate, hopefully one day they can eligible for any career they desire.

This is really interesting! I had no idea there were different types of color blindness. I had always thought there was only one type: red-green colorblindness. I was, however, aware of certain jobs not hiring people because of this. Some jobs require that one pass a test (FALANT test) in order to acquire certain jobs but like you said, while it is sad, it is understandable from a safety point of view.
