Actually, it might be a result of stress. I had it happen once with my yellow colony; they reacted badly to a dose of Panacur (or perhaps a resulting ammonia spike due to planaria dieoff) and I lost one or two shrimp - the rest turned bright green. After I did a 90% water change and gave them a few days to recover, they were back to yellow.
Could be something about breeding that caused stress, or it could be a result of something in the water, and the berried females are just the first to react b/c they're more sensitive. Or, as others have said, maybe you're feeding them blue dye without realizing it (in that case, though, I'd expect all the shrimp to be green. I'd do a water change just to be safe.
