Hi, thought I'd give feedback as I really appreciate it when games implement these features 
I have moderate Deuteranopia, but my monitor is dimmer than most which might affect things too.
The shapes are great, and the minimap is very very nice in both Alternative shapes only and with Deuteranopia.
The two issues I have both only really apply to the system map. The first is that the hidden chests hide well inside the yellow enemies, and stand out much more against red dots and diamonds. The second is that in every colourset enemies and asteroid have a... similar shade. It's hard to describe but enemies don't stand out like they do on the minimap so when I check the map quickly to see if it's safe in front of me I often miss ships near asteroids.
I suspect it might be to do with the fairly pastel(?) colours. Bright, shiny, green is often easier to distinguish from brown than dull, flat, green, although friendly ships are the only dots which makes that easy enough.
