Layer meshes by displaycolor

I have imported an OBJ-file containing a large number of closed meshes with varying diplaycolor and transparency and I wonder if anybody knows a way to change the layer of the meshes based upon their color and transparency?

Maybe SelColor works here?

Worked great, thanks. I will do this a number of times and wonder if this could be automated?

Hi Max - it can probably be automated - can you post or send me via PM one or two of the obj files?
