Hm, no, I can't sign this. Take a white light beam and split it with a prism. You'll get the full range of colors, a continuous color space, not limited to 'steps' or a certain amount of colors - this 'limitation' is artificial for the computers... Depending on the film you will use, you can even capture infrared, ultraviolet and many colors invisible for the human eye.
But to keep things simple, yes, you are right.
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> CMYK can't accurately reproduce the RGB colours from the fills at the top. <HR></BLOCKQUOTE>
The reason is not the CMYK colors, but the bare fact that the CMYK display is only a simulation of how a color print will look. There is one single big difference between art and traditional media like painting and electronic media like TV and computers:
TV and computers build the colors from RGB, and they are active, meaning the illuminate a screen coated with phosphor or tiny LEDs. The colors actually emitt the light, they 'glow'. Whereas in traditional media like painting, printing, photography the colors are reflective, meaning we can see or perceive them only because a relatively homogeneous white light (sun or artificial light) is directed to the carrier of the colors / pigments, which reflect the light and throw it back to our eyes, absorbing the rest of the spectrum (uh, tough one here for me, sorry if I can't explain in better in English).
Without an external light source the human eye wouldn't be able to see the colors at all.
But this simulation is a compromise. Depending on the carrier medium in print the colors appear bright or dull - the composition of the material and the coating result in a big difference of the final print.
It's kind of contradictory to show reflective colors on an active, light emitting medium. Would be the same as if you would try to simulate computer screen colors on printed paper ;-} - it wouldn't work in darkness.
A nice example: If you want a brilliant white paper surface, what would you do with the coating? Add more white? No, there is nothing 'whiter than white'. Instead you will add up to 3% soot (!). That means adding a matte black to white will end up with the ultimat white. That's one of the weird things in the paper production processes (I learned this while producing a 30 minute documentary film about a paper mill in Scandinavia).
In short words: if you enable the print preview mode, you will see the simulation of reflective colors on an active display, perceiving colors as they will appear on a carrier medium.
Are you confused now? Well, then I should start with the color perception of the human eye compared to the color perception of a parrot's eye, but this will be too long for a post in this forum ;-}.
Thumbs up, it's a colorful world - let's enjoy it!
