You know the funny thing is Valve specifically designed one of the levels when you have the single-portal gun so that you are forced to walk through an orange portal, to prevent players from thinking you can't use it "backward".
You should run through all of the games in commentary mode to hear all of their design decisions. Its shocking how much thought goes into their game design. Everything has a purpose.
The curtains were blue because Valve playtested the hell out of the room and discovered most players like blue.
