plus is minus and red is green
My brother in law is an electronic genius and he is also colour blind. He used to make a joke about it by saying “it is all very simple, all you have to remember is that plus is minus and blue is black. He left me feeling uneasy about his hobby.
Still… if you read Janaina Wittner and Daniel Goldschmidt’s article on

A good read.
