Part of the issue is that the diffuse texture combines two pieces of
information - the reflectivity and the color. (Compare: dark red vs
bright red - same base color, but different perceived reflectivity.)

But well, if I had to invent a way that only uses that diffuse texture,
I would try to extract these two bits from the combined texture color
(like, normalize color value + use factor relative to original color as
the reflecitivity).
