I've heard of colorblind cubers using alternative color schemes that have more contrast for helping them distinguish colors. WCA also allows textured cubes for blind solvers (obviously these aren't allowed in the blindfold event)

I agree, it would be interesting to see what techniques evolve. We can get some hint by looking at unofficial multicube records (most solves in 24 hours, most solves while holding breath underwater, etc). It would definitely wreck zz. Not sure which method would come out on top though. I've always been biased towards petrus so am enjoying coming up with reasons why that would potentially see a boost (although I doubt it would actually come out on top). I doubt we'd see many x-cross starts among CFOP solvers which I think is sad. I'm also wondering how this would effect color neutral solvers compared to solvers that stick to a specific color cross. I spent a month switching to be color neutral before my average times got back down to pre switch average.
