All of my rosy barbs, who were bright red, are now all brown, or have a very light tinge of red. Could they be trying to blend in with the pond liner? The only red left is a little on the fin and on the belly.
 
In my experience the brightest rosy barbs I have ever seen were pulled out of a pond.

How big were they when you put them in? Is it possible you got imported hormone fed females? They should color up like males, but usually turn back. Also what variety are you keeping?
 
That pic is kind of hard to tell. They might have been juiced. MT isn't legal to use in the US, but It is legal to import juiced fish.
