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.
Come to think of it, the people I've met with color blindness have been male. I do hope scientific advances increases all kinds of opportunities.
Yes, some animal gene projects have been successful.
