I can see darker or lighter skin well enough, and actually, more contrast is very helpful to me in keeping track of the characters, especially if they're all wearing interchangeable business attire. I could probably sort characters into the 'standard' black/white categories with decent accuracy.

However, I have a very hard time remembering all the 'race'-related media tropes, and knowing which one is meant to apply in what plot-point. The whole thing is so utterly surreal, it's hard to take any of it seriously.
