Hii, 

These are the professions where colour forms the important part of their job,

• Electrician 
• Doctor 
• Scientists
• Defense forces including paramilitary forces.
• Pilots  :both commercial and airforce
• Engineers: specially the non coding types.

colorblind people should avoid these professions, where they find difficulty in identifying and distinguishing between the different colour because this will not only cause damage to their profession and career but also unsafe for the people around them 

Hope this will help. 

Good luck!
