Color Changing crays

Does any one know why crayfish change their color after molting, I had several common crayfish, that were brown, but my smaller ones have changed their color to blue after they molted.

could it be the types of food you are feeding them?

I found some other sites that also talk about diet and environment. They also mentioned that a lot of them will change colar as they mature and when they molt(sp).

you gave me some good info last night and were helpful so I hope I can return the favor.

I figured it had alot to do with the blue gravel, But I like em blue.lol Looks like you researched your blue lobster alot, I saw a picture of one, which is what gave me the idea of keeping crawdads.
