RGBS: Color Spaces For The New Millenium
Snowfox writes: "Crosley Bendix, Director Of Stylistic Premonitions, U.M.N., has this excellent article explaining Squant, the fourth primary color. He managed to get his hands on a new Apple Quicktake 1500sq, in advance of the US release, to snap some photos. You can view them with the plugins available on the site. -- Sorry, no Linux plugins. :( -- Seeing a new color jumping off your screen is a real head trip though. Just try and imagine a color you may well have never seen before." While it's true that no Linux plugins exist yet, a GIMP plug-in can't be far away. Considering Squant's olfactory characteristics, that might not be the greatest idea, though.
My friend frantically calls me up and says to me "There's a big problem!!" I say to him "What?" he goes "I can't install the Squant plugin! I can't see squant! " so I say to him "uh... that's a joke. you know that right? " He replies that I'm an idiot, and after about a minute realizes he's wrong. Looks like someone reads /. too religiously.
Looking for Madam Tetrachromat
Actaully, if you look at the wavelength of Red, Green, and Blue you will notice something interesting.
Red is a greater distance higher than green than green is to blue, meaning that a wavelength between Green and Red would in fact be an altogether fourth colour, which is exactly what the Tetrachromat would see.
How their brains interpret this data however is totally beyond explaination to those of us who have "normal" three colour vision.
You can't say it's like another shade of red, because saying that is like saying green is another shade of blue. It is not.
The fact is, there is no language to explain colours to someone who can not see them. It just can't be done.

Personally, I'd hope that as our electronics D/A converters get more accurate, we'd shift to more colorspace resolution. 48bpp (16bppR, 16bppG, 16bppB) is the next logical step, along with a 16bpp alpha channel, to give a natural 64bpp step.
While it's true that the human eye's sensitivity is right around 200 levels of gray, unable to see finer distinctions, a human can very easily see the mach banding in ramps of other more subtle hues in the 24bpp color resolution space.
I've heard Hollywood typically uses 48bpp for the special effects graphics, and there's some 16bpc (bit per channel) features in GIMP and Photoshop, but I don't know much more about how we're advancing for hardware support there. I just want better colors!

Have a look at this page from Adobe's online guide to colour theory. It's very informative and should help clear things up.
Actually, no, the primary colours of pigment are Cyan, Magenta, and Yellow. The whole RYB thing is a myth propagated by artists and ignorant high school art teachers over the years, which has nothing to do with the actual physical characteristics of colour and how our eyes perceive it. I had this sort of thing ranted at me for a semester in Colour Theory class, and it's actually quite interesting. This my help clear some things up.
Man, you haven't lived until you've grown octagonal rods in your eyes and seen the eighth color, octarine, the color of magic.
Of course I can't describe it to you, but it's sort of a purplish-green....

Not Likely...
If memory serves, it is believed that only women are capable of having tetracromatic vision. Which (if memory serves) is normally seen as an extra shade of red. Tetracromatic people can often tell that items, which seem to match to ordinary people, don't. ie they can tell the difference between a true black ink and a cheap black ink made of cyan magenta and yellow inks.
Sadly Tetracromatic women generally will have color blind male children.
But this is not a story of gene transplant for geeks for four color sight.
And there was a story a while back about a new basic taste being "discovered" (basic tastes being sweet, bitter salty), this being a flavor that is more common in asian foods, and is found in many oriental dishes.
But what about re-engineering the monitors to take advantage of the new discovery?
