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

The TV might look great, but as far as adding yellow, it's gotta be pure marketing bullsh#t. The RGB spectrum already has yellow (it's just not in the acronym), so they're not adding anything.

As humans, among other critters are trichromatic beings, meaning we perceive color by subjective appraisal of differences between long medium and short wave light, including yellow now should add to the overall color schemes we might see.

Green and blue are close to one another in the light wave bandwidth, with Red and yellow being more diverse. Longer, and shorter, respectively.

Red yellow and Blue are the basic colors I recall being taught about in school. having less diversity in the basic colors chosen for projection by using two similar ones and only one more different type always bugged me.

Too bad they waited till now to include more diversity by adding yellow.

All that said, it comes down to the rods and cones in our own eyes, so in the end, I suspect some will be quite taken by this new application and some will not be quite so gladly affected.

As stunning as is what can be gained from using only 3 or 4 primary portions of the light spectrum itself, just think what could be if six colors in all should comprise the basic format from which the image is derived. Allowing for a still greater and more even and naturally displayed image.

Two from the long end, two from the middle and two from the shorter end of the light wave span itself.

shouldn't be cmyk? (cyan magenta yellow black)

No. Cyan/magenta/yellow are the primary pigments--the primary colors of *reflected* light. Red/green/blue are the primary colors of direct light.

The division of red/green/blue is arbitrary and the lowest number of colors possible to *approximately* cover all of them. This method takes the visible light spectrum and divides it equally into three parts; the visible products are red, green, and blue. But if you look at a lot of TVs and even after you adjust them, you'll find that some favor greens, some are redder, and some, no matter how you twiddle the knobs, just can't do neutral grey shadows or believable skin tones. Or sometimes there's a persistent green tint that--by the time you adjust it out--goes straight into overly red.

This is because the 3 color system works, but it isn't perfect. Lithographers have known this for nearly 200 years. I have hanging in my living room a limited edition litho of a pair of Siamese cats. Standard color printing requires 4 colors of ink--magenta, cyan, yellow, and black. This litho used 6 colors--the standard four plus specially mixed inks of blue and green to more accurately capture the color of the cats' eyes and the foliage surrounding them as depicted in the original watercolor painting. The lithographer wouldn't have gone to that trouble if the standard 4 inks would have sufficed.

One could create an entirely different color system by dividing the visible light spectrum into (for example) six segments. Then there would be six different colors than the three primaries we're accustomed to. Color renditions would be more accurate as well.
