Ben,
Genghis' reply is spot on! Go back to college and get some aviation related qualifications. Never mind if it's boring. You REALLY want boring - try the CPL or ATPL ground exams!!! Nobody but nobody will tell you that they enjoyed any of that, but it's worth being bored for a while if the end result is worth it.
I wouldn't pin your hopes on a cure for colour blindness, as I think it's caused by some missing receptors, and I can't quite think how you'd remedy that. Though that doesn't mean it can't be done in the future. But you'd be better off looking at what you can do now, and you've got loads of useful suggestions here. Good luck!
