For what it's worth, I once spent mucho dinero buying a piece of that pink M. digitata but after a few months under captive conditions and Iwasaki lighting it turned into your garden variety purple (or brownish with purple tips). Long since traded or given away that particular piece, so I have no idea if it ever returned to pinkish under different lighting.
