I can't believe I've found an instruction manual that officially advocates sorting purely by color ;) Even if they do separate Technic out. Good advice on no Legos on carpet, though Edit: clarifying, since the down votes are already coming: I'm joking, folks! While sorting by type first is easier to find pieces, clearly sorting a single bag for a small build by color is different than sorting your entire personal collection by color only :-) I thought it was a funny example by Lego ...
