With Red-Green colour-blindness, I have found that a multi-stain approach works for example:
Often the ZN counterstain used is light green. A second ZN stained with Loefler's Methlene Blue for comparison seems to help. The same can be done with the Masson's Stain (compare the Fast Green FCF or the Light Green collagen stain with the Masson's Variant using methyl blue, aniline blue or direct sky blue) If the Twort's variant of the Gram stain is used, compare with a Brown-Hopp’s Gram Stain. Those with Red-Green colour blindness seem to compensate excellently and I have found no issues with staff (including pathologists) in differentiating the two colours.

I know, because I already work for 35 years in the histopathogy. Just a few things that causes problems for me: Grossing: I describe tissue in the way I see, mostly I call something with 2 colours, p.e. “ the serose is brownish grey” (while collegaes mostly mention 1 colour. But I can see the difference between normal and abnormal tissue, that’s more important. Embedding: only skin biopsies is it difficult to oriëntate when the colour of the dermis is the same as the subcutis (in my eyes ;-). So with that, I ask my collegaes to embed these biopsies for me. Staining: When I have to do the stainings, I just have to following the protocol. In the SOP, There is always a example of the control slide. I just have to compare the determination with the example of the SOP . These are just a few example. A colourblind technologist could be a great technician, with just a very small restriction.
