This is an interesting attempt at adapting a game for accessibility. It’s something that can easily be overlooked when designing a game targeted to the general public.

That is indeed interesting. I never even knew there was about ~8% colour blindness in males (mostly red-green). That’s quite a high number, much higher than I would have guessed. I often follow standard HCI (human computer interaction) practices, but this person’s efforts makes me think I should go even further. Having those simulations would help illustrate what something looks like through colour blindness. That would certainly help determine if I missed something.
