Currently, three different colored materials (Paints, then metal ingots) are needed to upgrade brown hull... Could someone please, PLEASE reduce this to one thing... orange, perhaps? I know that it isn't fully realistic, but it would make things more fair. Right now on EE I'm using brown hull I had from before the blueprint update, otherwise I'd have given up using brown hull for anything by now and just used gray or something since setting up the factories for brown is a bit ridiculous.
