Are we Colour Blind or are the people we think are colour blind not actually colour blind

Ive been thinking about this for the last couple years are we potentially the ones who are colour blind and the people we think are colour blind are normal.

Ive never found an article proving that we "normal people" aren't actually the colour blind ones.

You could think reverse psychology on so many other topics as well, it's not just color blindness, it could be deformations, etc.

 

No, people who are colour-blind to some degree have deficiencies in various cells in their eye. There's a loss, not a gain, of function:

There is the possibility that some people can see more colours than average, though:
