Ok so i have always had this theory that if you were colorblind and saw the exact opposite of the color you are seeing or if your colors were swapped like if red was blue ,yellow was green etc... down to the tee that you would never know that you where color blind because someone would say blue and you would too but you would see red. "you would never know unless you looked at a color blind chart but then i dont know either u might still not know"
I have often wondered if everyone else saw colors the way I do or if another individual sees green the way I see red- that is if I were to somehow become hard wired to the visual centers of their mind while they we4re looking at a lawn for instance and registered visually a color that I know as red. Other colors could be swapped; blue and orange, yellow and purple... but they'd know nothing else- their world would have been colored that way since their birth. Our ability to describe a color is limited through either the label given the color (red, blue. etc.) or something that is typically one color (sky, grass. etc.). A person who has never seen will not know the meaning of grreen or red or whatever... and good luck furnishing via language something that is purely a visual experience.
Unedited OP: It's actually not as indeterminable as you would imagine (there is what is called "Ishihara color test" which is used for that particular purpose). Below is a link to Al Seckel's Homepage of Illusions, Perception & Cognitive Science, also very interesting to look at in the context: www.illusionworks.com
If a rainbow looks Gay then you aren't color blind. Because all those colors bending together is just about the Gayest looking thing there is. Other than two guys in short shorts holding hands skipping down the street. That's gay
