AnswerNo it does not. You can paint Space Marines any color, specific colors are not claimed by chapters.
You can do it yourself, all you'd need to do is add a few spikes here and there, and then it's all up to how you paint it. If you paint on a few demon faces here and there, as well as the mark of Chaos, they'd be convincing enough to pass as Chaos Space Marines.
It depends where you are in situation: Melee Space Wolves Range Space Marines Psychic Space Wolves (only just) Vs. Vehicles/Light Infantry Space Marines Vs. Heavy Infantry Space Wolves Look Unpainted Space Wolves Paint Scheme Look Space Marines All-Round Space Wolves (I Reckon)
Depends what you mean by the term hard to paint. Some Space Marines have some fiddly details but altogether I say no.
Umm...it's yellow paint...It was probably used for highlights on the space marines models for certain wargear.
