How long does it take for shrimp to revert color if you don't cull?

Heyo, I just started a colony of 10 cherry shrimp & I plan on letting them breed uninterrupted in my 44g. I don't plan on culling & I heard that they will revert back to a brownish color if you don't take out the less colorful ones. I'm okay with them reverting back but I'm curious as to how many generations they will stay a redish color.

I am still waiting for my first shrimplets, so I cannot answer your question; but this post indicates that the tendency to revert to browns might be overstated.

That was an interesting read. Thank you for linking it!

That bright yellow female is no longer berried ... I have shrimplets! I saw some swimming around today so I'll post again when they're older and I can see their coloring. Very exciting!!

I don't believe it's possible to give a definitive answer since there are too many variables, starting with the genetics of the shrimp you started with.  In any case, I'd expect to keep getting some red shrimp for quite a while.

The issue is that people look at it from the perspective that all neo mixes will do this at the same rate. It all depends on the color morph and how close they are genetically to the wild type color and the depth of said wild type color. Mixing certain color types introduces browns sooner down the line than others.
