Can I attend Army Ranger school if?

[U.S.xARMY]

I am "considered" color blind on paper, but I can differentiate between colors... I'm enlisted and leaving for boot camp in 2011. Don't worry, I know what Ranger school is and what it requires. I actually worked with a Ranger who was in the Army for a few years, so I'm not some uninformed kid who wants to be G.I. Joe... Anyway, yea, the Army has me as color blind. I'm just hoping that wouldn't stop me from applying to Ranger school.
