God forbid that you & your pathologist see the same color
differently...I go through this with my boss every once in a while. An
H&E slide will look just fine to me, but to him it's too pink, whereupon
he tells me to go clean my glasses, change out the H&E and restain the
slide. :oP Fortunately, our lab is a university research lab, so we
don't have to undergo CAP inspection.
