He seems to be totally confused on the concepts of the frequency of
light,

No i claim that when you take a photo each granular silverstoft
depending on wavelength "NOT THREE" take on one color in the visible
spectra.

And what wavelength is brown?

What wavelength is white?

You are quite right that some colors is not represantable as separate
wavelengths like brown, orange etc

I didn't say orange. Orange is a single wavelength, lying
between red and yellow.

"Wikipedia"
But what is representable is 2^24 wavelengths/colors "given a
quantisized 24-bit graphic card".

As combinations of R, G, B. These by the way are not all
the colors you can perceive. Monitors aren't perfect. And they
can't reproduce pure rainbow colors at all.

Probably it would not be a problem separate even more wavelengths in
the actual terahertz range.

My guess is that one pixel can not show brown or orange "now i am
guessing" you would have to mix a couple, because brown and orange as
you say is not single wavelengths.

One pixel can't show orange because the source pixels
are only red, green and blue. But one wavelength can be
orange.


Pick a number between 400 and 650, the range of the visual
spectrum. It must be one of those, right?

I admit that some "APPEARANT" colors need component frequenses but
then they are not really colors are they, you ever saw a brown or
orange part of a rainbow?

Orange, yes. It lies next to red.

But at any rate, you're starting to glimpse the truth. The rainbow
contains
only pure hues, not every color we perceive. So isn't this at odds
with your statement that when ever wavelengths combine, the resulting
light must be some new single wavelength?

MOST apparent colors need component frequencies. The
only pure colors are those at the edge of the chromaticity
diagram. Every other color we perceive is a blend, a
sensation our eye creates from the three responses of our
visual receptors.

Again, LOOK at the diagram. This was mapped out decades ago.

What wavelength is gray? What wavelength is beige?
What wavelength is pink?
