I wanna to try make material like you 4mykids ,but I would to get to the mix some colours - when I will have , for example: Lasius flavus ,it can be nice in ,also for example: in black material ,or somethink like that. Everyone have white ytong ,but why? It is possible to get colors to your mixture? Because ,on white material is easy to see dirt ,on black it is maybe better. It can be good topic with experience of build formicariums. But now we must wait for some pictures of your material 4mykids

,if it is possible
Thanks
