AIUI there are not only different forms of color blindedness but also
different levels. Putting that all together means a very large amount
of complexity.

Likely an easy path to avoid most difficulties - - - use only strong
primary colors - - - does that solve the possible issues - - - nope
but those that are color blind have learned to cope with those specific
issues (I'm thinking of red like in stop lights).
