Hi Oaksey,
I hate to say it but you can't get a Class 1 Medical if you are colorblind. I have a friend that is colorblind that flies though. He had gotten a Class 1 Medical for the first time 10 years ago and then couldn't pass the color test recently. He had to get written permission from each state that he flies over or lands in. But the waver is only good for 1 year. After that it is not looking good. He flies cargo commercially within a Nordic country. I don't think any airline will hire someone that doesn't have a class 1 medical and needs all the special attention. Sorry, just my opinion though.
Good luck,
GC
