Mark Brown’s “Designing for Disability” series seems to be very comprehensive and well researched. I’m moderately colorblind and feel very well represented by this video.

It reminded me of the game I most wanted to love but just couldn’t play: Puzzle Bobble. If a level had both blue and purple bubbles, I was toast. Even though each bubble color had a different shape inside, the differentiation wasn’t enough for split second decisions.
