The answer is yes - you can be colour blind and become an airline pilot, however, it depends on the severity and what colours you can recognise.
Your colour vision will be assessed at your inital Class One Medical (a requirement to be a commercial airline pilot)
"Applicants shall be required to demonstrate the ability to perceive readily the colours that are necessary for the safe performance of duties.
Applicants shall pass the Ishihara test for the initial issue of a medical certificate.
Applicants who fail to pass in the Ishihara test shall undergo further colour perception testing to establish whether they are colour safe."
