Thread: A new color....

I guess my point is that you'd need 4 dimensions to represent the colors that a tetrachromatic person can see, but only 3 for trichromatic persons, so I don't think you can just map tetrachromatic colors to trichromatic colors..

First off, it is impossible to see "new" colors in a dream. See O'nus's post in the tutorial section, or do a search. I remember making a couple long posts about this a couple years ago.

Secondly, if you could see other forms of electromagnetic radiation, it would NOT necessarily manifest itself in the visible radiation part of the spectrum. It might have a "color" to it, but it would most likely have a unique attribute. It seems people seem to think it would simply look like a color because that is all we can comprehend, and when we take pictures that can detect other forms of electromagnetic radiation, we see it manifested in wavelengths we can see. It is impossible for our minds to comprehend what another form of electromagnetic radiation wold actually look like, simply because we have never seen it before. It is the same way with imagining a "new" color. It is absolutely impossible to imagine a "new" color in our brain. Perhaps another form of EMR would be a color, but it would be a color we've never seen before. We cannot comprehend what it would look like though.

I don't think the Lounge is the proper place for this thread.

in case you have some mutant-human-being who is able to see all the color spectrum (meaning he/she has the necessary neuron-photo-sensors in his/her eyes) it would be impossible for the brain to filter all that into a clear and use-full image ... cause u have all sorts of frequencies around you ...

As I said, it it impossible comprehend how it would actually look. You have no idea what it would actually "look like" as we as human beings have never seen the EMR itself before. If everybody was deaf and somehow someone brought up the idea of detecting a small portion of EMR (that we call white light), someone like you might say "but it would be impossible for our brain to filter all of the frequencies into a usable image."

RGB is a useful model precisely because the eye/brain actually has red, green, and blue filtration. Color-blind people are missing one or two of these, which is why there are different specific types of color-blindness.

But beyond that, RGB theoretically can represent the entire light spectrum within its lower and upper frequency/wavelength bounds. Our visual processing uses this model because it works.

Having four primary color filters would likely not add any "new" colors, but only break up existing colors in different ways. If you look at printing processes, they use 3, 4, 5 and even 6 different primary ink colors to create all available colors. But going to six doesn't allow you any "new" colors for the eye... it may simply be better at representing certain shades available with pigment on paper.

Wow, so much science behind just one simple concept. well it wasnt really a simple concept. haha. well thanks for the explanation(s). it woludve been fun to have a lucid dream and try to concive a new color.

I'm sorry, but I fail to see how three numbers can describe every color for a person who sees 4 primary colors..
