Are you colorblind having decreased ability to see color or differences in color?
I am not colorblind but I have met people who are. 
Achromatopsia is known as total color blindness
Wow! I never knew the name for it. I wonder how exactly people with Achromatopsia view the world?
It is very severe and I believe they see the world in shades of gray.  Work is in progress for gene therapy.
If gene therapy results in success, I believe that people with Achromatopsia will feel like it's a whole new world filled with brightness and beauty!
Yes.  For those with partial color blindness it will provide increased job opportunities.  It affects many people, especially males.
