Hmm. The issue there is probably more a case of "wet vs. damp vs. dry".
Not sure how that would work, since you need a darkening of the color
where its merely "damp", to match that of the wet part, but without the
reflective characteristics... But, yeah, life, sadly, is often more
complex than is easily managed in what is supposed to be a
photo-realistic rendering engine. lol
