It is pretty binary. If I can't understand your slides because you have one set of points in red and the other in green I walk away and ignore your presentation.

Colorblindness also has very well established definitions. Note: learning what words mean should come before trying to redefine them.

Those definitions are mostly wrong. On HN (my experience) people associate colorblindness with and only with "red-green color blindness". This is obviously wrong, or at least not well defined.

It's not binary. There is a range from not colorblind to minor defience to fully red-green colorblind
