Understanding Color Perception and the Brain: The Role of Television Frequencies

[luckis11]

The television radiates only (at most?) three "colors"(=let's say frequencies)? Then how does the brain translates two (neighbour?) "colors" into e.g. yellow color?

Color=the feeling we actually see.

A link answering that would be marvelous.

Interestingly, http://en.wikipedia.org/wiki/Color#Perception", most of the colors we can perceive can be recreated, from black (all phosphors off), to various colors, to a balance of all three, which we perceive as white.

When it comes to recreating colors between the primary colors, such as yellow, simply adjusting the neighboring frequencies, in this case green and red, will produce an interference pattern which our eyes perceive as yellow, just as if we were seeing a pure frequency between 590–560 nm. In fact, if you look at http://en.wikipedia.org/wiki/File:CIExy1931_fixed.svg" , you'll see the primary colors as well as all the colors between them.

I hope this helps!

This variation of intensity causes the frequency of the yellow, before or after the light reaches the eye?

At least, can you explain to me what this means?

There are twelve unique ways to sum or contrast three cone outputs to define hue: our vision uses six contrasts, plus a single luminance sum. This requires a unique nerve pathway for seven different signals; similar outputs in a four cone system would require at least 15 contrast and luminance pathways.
