Colorblind friendly Tollenkar Map?

[Shadekeep]

I built out the Tollenkar map in Shamat as one of my first proofs of concept. I did a quick test yesterday of peeling the layers out, and there is a LOT of whitespace in each individual level. So yeah, I can see why they did the layered map originally. It is a design conceit that does rather force one to minimise overlap between levels and such, and really isn't suited except in special cases like this one. But it's a pretty clever solution nonetheless.

I'm curious now as to how many of the colours in Shamat are not distinguishable to colourblind folks. (And yes, I know there are several varieties of that condition, each with different issues with particular colour groups.) I'd like to revisit those colours to a more optimal set that everyone can use, if possible.
