A blasphemy....I know....

Recently I had occassion to go to an audio/video store, which is usually painful for me--but I went to help a friend purchase a new TV.
I saw the new RGBY, note the added Y in that statement.
Sharp has a new unit, (others I'm sure to come) that has Red, Blue, Green, AND YELLOW!
The difference at first, until my eyes adjusted to the store and the 'millions' of other TV's seemed notable, but not revolutionary.
WRONG! After about 15 minutes of comparing others TVs as my buddy wasn't going to jump and pay more--I focused, (no pun) on the RGBY. WTF!!!!
Man this set is really something. Colors such as rich browns, and coral colors, and even the infield grass at the Ky Oaks was brilliantly better.
Anyone else seen this???

Back to my first love now, AUDIO and WOMEN...
(Not usually in that order)lololol

some of you are confusing the mixing of pigments to produce color, and spectra of light. They are not the same thing and do not work the same way. Mix all the colors on your palette, you get a dark, dirty gray. All the colors in the spectra combined equals white, clear light.

Most monitors reproduce only about 70% of the color spectrum in an NTSC signal. The best ones (e.g., Sony Qualia) produce the whole enchilada. You don't know what you're missing until you see it done right, as apparenly Larry did.

I was under the impression that the addition of yellow was motivated by upcoming new energy efficiency regulations. The addition of yellow permits a brighter picture while using less energy. Currently brightness unto itself isn't much of problem for most typical applications. Meeting the new energy regulations and maintaining desired brightness might be problem.

Well, someone said 'total marketing bull*hit', that may be true of many things retail, but the 'color shading difference' sans marketing on this unit, calls for it to produce 256 colors plus one more factor of 256 making the total of shades, not in the millions, but into the >1Trillion color shades.
I, without knowing somehow fealt that the colors were more approximation and not the full range of color that is shown by sunlight or a halogen, and that is apparently true, if we're to believe that the shades of color reproduction have increased by such an order of magnitude.
I only know that there WERE more colors, and that sublte 'combinations' of others were rendered with more subtle shadings. My eyes, like my ears didn't lie to me.

First off, pigments are a completely different conversation than the RGB light spectrum.

The reason I say the extra yellow color is marketing bulls#t is because RBG are the primary colors of the entire spectrum of light that our eyes can see. You get every other color in the spectrum by mixing them together. When we see the color yellow, we're actually seeing a mixture of pure red and pure green. That's what yellow IS. They can't add and extra yellow color because it's still red and green mixed together.

The question is not whether three RGB lights with variable intensity and backlight can produce yellow. They obviously can. The question is whether or not adding a fourth light in the way Sharp does produces a better picture. The newest large-screen RBG LCD TVs look better than the first RPTVs which came out but it is still the same RBG. The goal is a better perceived picture, not satisfying purists' theoretic ideals.

Anyone who has ever painted knows that you can use the three basic colors and white to get to everything, but I have known any number of painters over the years and none of them starts a painting with only four tubes of paint in the box.
