I haven't done any research on this so I am a little into guessing. When
radiation hits a surface some of it is reflected and some is absorbed. The
more radiation that is absorbed (and thus less reflected) the darker the
surface, a black surface absorbes at least in theory all radiation. Now if a
surface is wet some of the incoming radiation will be used to evaporate the
water and thus less radiation is reflected and the surface seems darker.
