> Strip your design of all color It's harder than it sounds. If you have total color blindness, your mapping between colors and values might be entirely different from most people, or even other people with monochromacy. Color blindness in general is a pretty wide range of perception abilities. There's a classification but it's fairly rough. It's usually close to impossible to design something that makes sense for all colorblind people at the same time, because the types overlap heavily.
