So SAD. Illuminate me.

I've been aware of a tendency toward winter blues for many years, but this winter is really kicking my ass already. I think I'm ready to look into a little treatment, and I'd like some advice. Yep, I've read all of the previous AskMes on this. [more inside]

Why do porous objects appear darker when wet?

Why do porous objects (wood, textile, hair, etc) appear darker when wet then when dry? A googling gave me this ("surface reflection and refraction"), but that doesn't sound entirely reasonable, as it merely talks of light being scattered, but the light in question is already diffuse. This also gives some suggestions, but nothing conclusive. Any chem/physics MeFiers know this?
