The simple answer is that a colorblind person should avoid professions where correctly identifying a particular color is critical to their profession and safe for others. If you are color blind It’s easier to list jobs you can’t do because you can do nearly any job regardless of color vision.
Firefighters, police officers, a lot of military positions, pilots, and astronauts are the main things you can’t be as a colorblind individual and you will often be outright rejected if you tried to apply for them after going through a medical screening.
I think you know your limitations better than anyone else, & that you should focus on your passions & strengths.
