Absolutely correct. This very thing is what has for years led many people to
believe that Remo Pinstripe (two-layer) drumheads are filled with oil, since
the patterns look much like the colored patterns of oil floating on water.
This in turn prompted the good people at Evans to actually make drumheads
that are truly filled with oil. They sound like crap.
