Can I be in a combat unit if I am colorblind?

My goal in life up to this point has been to get into the Naval Academy and become a marine officer. I have busted my balls to get a 4.0 and do all the leadership and charity, as well as letter in football and track. However, I recently discovered that I was slightly colorblind. It is so slight that i can actually make out some of the numbers on the plates that colorblind people aren't supposed to be able to see. Does this mean that I cannot be in a combat unit of the military/ is everything I have done up to this point for nothing?
