I am an 18 year old local boy who loves flying a lot more than others. Some years ago when I do a body check, the doctor says I have colour weakness, and he said it will affect my choices of jobs in the future. I want to know if colour weakness will rule me out of a career of flying jets and even just getting a PPL? Or will I be rejected from both CX and KA CPP or even ATC controller in first sense? I hope someone will give me an answer as I have to decide what way i should go in the future, thanks in advance!

And I also heard from another part of this forum discussing about the lantern test for quite sometime, how exactly does it work? Does Hong Kong have such a test?
