Blue velvet shrimp breed the least true of any Neocaridina color I've kept. You simply have to cull or your population is not going to stay blue. Culling doesn't have to mean killing the shrimp though. I have several tanks just for culls. In some there are fish so I don't see new generations, but in others they are the only fauna and will make more culls. Sometimes these are more interesting than the ideal color. Other times they tend to revert to gray/clear, so I've began culling my culls so to speak!
These all came from blue velvets (note the parent shrimp in the first photo):
Of course, what constitutes a "good" or "bad" cull is completely subjective and up to yourself to determine. But I endeavor to remove any baby that isn't blue by around the 1/4" size, so that they don't pass on their genetics to the better colored shrimp. If you don't have spare tanks set up (I highly suggest you do if breeding anything) you can always gift them to other hobbyists or your local fish store if there are still any of those left in your area.
