Designing for Colorblindness
For some people, colorblindness is a serious liability that closes doors on career dreams. It’s hard to become a pilot, train conductor, or pathologist if you can’t differentiate colors in critical instruments, signals, or tissue samples.

Luckily we have a tool that let me approximate what Jason was seeing. xScope’s vision defect simulator confirmed that Tot’s colored circles had serious issues.
