RGB to become RGBCMY

elgatozorbas writes "The basic color elements of television have not changed much since 1954; a half-century after RCA introduced the first color set, the RGB (red, green and blue) system used then still prevails. But Israeli company Genoa Color Technologies has broken the RGB barrier by adding one to three primary colors such as yellow, cyan and magenta, thus expanding - from 55 to 95 percent - the coverage of the visible color gamut. The promised result of this multi-primary color (MPC) technology is a television picture that, with its truer, more vibrant color and brighter image, looks more like cinema than video. Also covered in IEEE Spectrum."

MPC: possibly the next standard?

Does this mean I should hold off on buying an HDTV?

This will be great for Tetrachromats

It's almost enough to make me wish I was a mutant mother of a color blind son.

Nice, but still shortsighted

A truly revolutionary idea would be to include and project IR and UV in addition to RGB/CMY. Even though our eyes can't exactly 'see' IR and UV, they still form an important part of our realistic image perception. It's not unlike sounds above 20-25kHz in pitch; we don't 'hear' them, but our brain perceives them nonetheless and they are used for stereo imaging of a space.

Those sounds are also felt by other parts of our bodies than ears. I once rescued a small bat, and while it was recuperating, from time to time it would open its mouth and squeal its echolocating squeal. While I couldn't hear it, my partner and I could feel the noise in our chest & neck. I also spent some time videotaping the bat as it flew around the room ready to be released. Whenever it did its noise thing, the levels on the VCR shot way up high and all the other audio dropped out. Powerful stuff, and while it's still sound it was perceived in far different ways than just ears.

CMY are really "combinations" of R G and B.

This is false. C, Y, and M are different wavelengths of light from R, G, and B. Because the human eye only has receptors for R, G, and B, we can't distinguish between equal quantities of R and G and a single wavelength in between the two, namely Y. In other words, we are able to trick the eye into perceiving a full color spectrum using only three different wavelengths of light.
