It depends on their kind of colorblindness.

I see green lights as white, which is fine most of the time because of the order.

The exception is when there's a lot of glare from the sun setting behind me, and I sometimes can't tell if it's green, or just the sun reflecting at the right angle. It also washes out the red and yellow, making it harder to see if they're lit.

I am the same--green traffic lights are nearly white. Normally, it's enough to know it's not the red or yellow light. Sometimes at night--face with an array of white lights in the distance--it can be an issue.

At my last eye test at the RMV, the clerk tried to tell me I wasn't color blind. I mean, sure, I've been able to drive with it for 40 years, but I know damn well I'm color blind.
