Explanations that work for whom? I can't speak for electromagnetism or physics. What I can say is that for years I felt like I didn't have the least bit of clarity on color modeling until I referred to Maxwell's primary materials, which are cited by just about no one sadly.
Could you explain this a bit? (Excuse me if I'm asking too much, I don't really know what you mean by color modeling, and how it connects to Maxwell - or maybe you are talking about wavelengths?)
