I didn't purge enough material on some of the colors (white/black to red), but overall I'm happy with the outcome.
Red - Protopasta Opaque Red
Blue - Atomic filament royal blue
White - Atomic filament bright white
Black - Atomic filament jet black
what's the MMU setup?
It's been a while since I set it up, but I think this was all of the changes. I did these mods while I was setting up and it was never fiddly for me like it is for a lot of folks.

Looks pretty great despite the flushing problem. I think I like the red color where "too much" white is behind it. Wonder if you could set the whole model to be white Infill or at least some white directly behind the red...
