How can we see brown color if there's no brown light?

Brown is just dark yellow mixed with red, dummy!

indeed, there is no brown light in the full spectrum of colors of light. perceiving brown as a color depends on visual context. if something emits or reflects yellow or orange light, but with very low intensity of this light/reflection relative to other things in the field of view (i.e. this orange/yellow light is dark compared to other things around), then it will be perceived as brown. same thing with gray. with the example of gray, it's a bit easier to imagine -- if you have your computer screen displaying a full screen of gray in an otherwise pitch-black room, you'll see it as white -- changing the screen to display all white instead of gray will just make it look like identical to simply upping the brightness of the screen

"Brown" is a blanket term for a muddy color, but color is relative. Yellow can look grey or blue depending on what is around it. "Brown" can be anywhere on the color spectrum and is not limited to one or two colors.You can have "cool browns" or "warm browns" just as you can have cool an warm blues. When mixing colors I was taught that you should not use just the "three primary colors" but instead 6 (each primary has it's own "cool and warm" swatch) so that "browning" and muddy colors wouldn't happen.

Because it's a phenomenon mediated by your own consciousness.

Brown and orange are the same hue. What differentiates them is the surround, if it's brighter than the surround then it's orange, if it's brighter it will appear brown.

There was a paper in 2014 that demonstrated brown and orange colors stimulate the same cells in the V4 area of the brain, suggesting those might be the cells responsible for detecting hue.

Light doesn't have any colors, it has frequencies. Colors are symbols representing certain ranges and combinations of these frequencies, they don't exist externally.

That's a philosophical statement and has nothing to do with science.

Searle claims that red light can be called red specifically because it causes a "red" perception in your brain.

So you’ve watched National Geographics Samsung Galaxy Brain Games i take it.
You’re wrong. Pic related.
Put it to the color dropper and you’ll notice that the puter tells you they are the same color. Take a pic with your phone of pic related then put the color dropper to it. They are different colors. Colors exist

Colors exist in the mind, not in wavelengths of light. There are many colors for which no wavelength corresponds.

You know digital cameras don't reproduce colors perfectly, right? Monitors don't either. The fact one of those browns is surrounded by glowing white light will undoubtedly change the color in ways beyond just the illusion, in addition to color, brightness, and contrast corrections done by the camera.

Also, mental states exist so... yes, colors exist. I'm not sure how we'd experience them otherwise. Inexplicable, but self-evidently true.

Brown is just scrambled light.
