For the toolbox puzzle, I see now that is tricky to get. Sometimes you have to make these things a bit easier at least at first. So what I would recommend is have all the roof tiles be brown except for 5 which are the colors in order you need them to be. Then like later on in the game you could have the more complex version of the same puzzle (the way it currently works) but you will probably need a npc near by to give a hint.
