What does it mean that color a “visual phenomenon”? Does color not exist outside of our brains?
In: 22
Color is a visual phenomenon because it only exists in our brains as a perception of the different wavelengths of light that are absorbed and reflected by objects. It’s like a translation of light into the sensation of color that we experience.

For all intents and purposes, no. The world has no appearance unless observed as appearance is a human construct of the mind

Color is a visual phenomenon because it is something that we can see and perceive with our eyes. Color does exist outside of our brains, but it is our brain that interprets the light waves that are reflected off of objects and assigns them a color.

Not really.
It is true that in some way colors in our mind correspond to wavelengths of light.
However there are also colors that have no corresponding light in reality.
We have three types of receptors in our eyes to perceive colors with, they each sense a range of wavelengths of lights and react strongest to the wavelengths in the middle of that range.
Our brain assigns colors to the combination of receptor types that are activated.
If two receptors with neighboring and overlapping ranges react to the same thing our brain decides it must be a color somewhere between those two and that makes sense. There is wavelength of light to correspond to that idea.
This ends up with us seeing a color for the case that the receptors at both ends of the spectrum react to something, but not the ones in the middle.
There is no light that is between red and blue but not green on the spectrum. However in our brain there is.
This is why the spectrum is a one-dimensional line, but the way we see color ends up with a color wheel, where the ends of the spectrum are connected.
It is that part which makes the sensation of color different from just perceiving different wavelengths of light.
