Sure you could… bring in purple and call that color green. If the other observer says no that’s the same color as the other one… then does it matter what name we assign to it?

White isn’t a color. Not even a corresponding wavelength to what we call white, which is a result of our eyes mixing different wavelengths.

If I see what you think of as purple when I see something green, the same will hold true for everything else you call green. There is no way to determine otherwise as color is purely subjective. I have no way of knowing what you visualize as the color green, only that you call it green, which leads me to think of what I am seeing as green, whether or not we see drastically differing colors.

If I had gown up seeing what I currently think of as purple but everyone said grass as green, I would simply believe purple is called green.

Color is a physical property of light that exists whether we perceive it or not.

This has now become a language issue.

The wavelength of light that we call “green” is an identifiable and reproducible thing… therefore it does not need an observer and exists outside of observers.

Again, green doesn’t actually exist outside of our noggins. We assigned wavelengths colors, they don’t possess any intrinsic color values, only wavelengths.

White is a color… c’mon!!!

The length of the wave is the intrinsic value. it exists whether we observe it or not. Our perception of it is meaningless to the nature of it. It exists without us.

Is it?

from Are Black and White Colors? | Britannica

If color is solely the way physics describes it, the visible spectrum of light waves, then black and white are outcasts and don’t count as true, physical colors. Colors like white and pink are not present in the spectrum because they are the result of our eyes’ mixing wavelengths of light. White is what we see when all wavelengths of light are reflected off an object, while pink is a mix of the red and violet wavelengths. Black, on the other hand, is what our eyes see in a space that reflects very little light at all. That’s why, if you enter a room with the lights turned off, everything is dark and black.

Yes, the wavelength exists, not color.

Yes… white is a color. it is a set of wavelengths.

Black is a color in that it is an absence of relfection… a property that exists whether we see it or not.

The wavelength IS the color … or our perception of it anyway.

No, color is the value our brains assign that wavelength, wavelengths possess no intrinsic value known as color.

When I am at work using a color meter to measure the wavelengths of light to determine what the camera is going to see… what am i measuring and why?

You are measuring wavelength, that your brain assigns the property of color to. Color which is entirely dependent on your physical receptors and brain. Wavelength is a unit of length, not color.

The wavelength is the color. It is measurable… reproducible… universal. It has all of those values.

It is very real. Not imaginary.

Color is a real thing.

No, wavelength and color aren’t synonyms. Wavelength is a measurement of length, not color.

No. I remember who I was told named it.

Interesting, can you provide an example?

Yes.

Trump lost the election.

I mean, in reality he lost it.

:rofl:
