I've always experienced staining on my clears with certain colors of dye ink - many of mine are tinged pink from reds, as you say. But this is more than a stain, really - you can't see through the stamp at all. Maybe it's the darkness of the ink. I was just very surprised. I have had no staining problem with dark dye inks and my clears.
It's not even that I care about stamps being stained. But when they are stained so opaquely that it's hard to tell when they are inked completely...
