Q: "Will you add a color-blind mode?" (https://www.youtube.com/watch?v=cm4fO5tDRag&t=2007s)
A: "I'm really not sure what can be done about it. We need to check what is possible. We will add it eventually."
There is a lot that can be done about it. Designing games with disabilities in mind does take work, but the good news is that color-blindness is among the easiest to deal with. I would like to offer some material for Game-Labs (and everyone) that will help understand the issue and what game designers can do about it.
