about Block reference?

[Anonymous]

I have two the same the dwg file A and B. I  create a new a single layer in A and  move all entities  to this single layer, then delete all  layers  in A  reserved for the layer and 0 layer . Then open the B, insert the block A to B. Now, everthing is  Ok except the color. In my mind ,  the color of  block A in B  will have the  same color because I set all the entities color bylayer,but it is not.

Why is that and How  can I set the color of  these entities to the  color of the singe layer?
