Thanks to everyone who answered the questions about melanin pigment. It 
seems most of you use a red pigmented chromogen to demonstrate IHC 
staining that will be easy to differentiate from melanin. I should have 
asked this question at the same time: do the red chromogens work all right 
with a hematoxylin counterstain, with a methyl green counterstain, or can 
I do without the counterstain entirely? Thanks again.
