Thank you!!! If you look closely, there's also a difference in the texture behind the text- we wanted there to still be something for colorblind players, but it's a bit subtle at the moment.
I had noticed that as well, but did not connect the dots until you mentioned it. If they were more defined abstract patterns, like futuristic arabesques or geometric linework that each fit the 'feel' of their respective narrators, I think that might make the difference a bit more distinguishable while still retaining the subtlety. In any case, I am sure that your final design choice will look great, whatever it ends up as.
