Is colour blindness a good thing?

i have been colour blind ever since i could use my eye’s. i was wondering if people think it is better to see all colours or if my limited paint chart of the iris helps me in a wider un-foreseen way.
i cant see purple, and shades as a whole just blur to there closet pastel colour,

also why is it when i tell someone i cant see purple they always point and say “what colour is that” to the nearest purple thong or hammack etc, i reply purple and they stare at me like im some filty liar saying “but you can see purple”
