Comment on Colours

In the actual, real, no the physical world, the one you wake up in before getting on the lighted rectangles, brown is a real color.

Except it isn’t “real” in the sense that it doesn’t correspond to a specific wavelength of light. It is impossible to produce a brown light; the closest you can get is amber. The color brown is context-dependent and only exists in our perception. To display brown on a screen you have to use orange, desaturate it, and make sure it’s darker than its surroundings.
If you pull up a solid brown image on your phone and hold it against a darker background (you may need to turn off the lights), you will see orange.

Right, but in real-life, not in producing a lighted color, just like looking: things are brown. A coffee stain, say.

If you were to point a spectrometer at something brown like a tree trunk you would see wavelengths corresponding to red and green light. That’s what I mean when I say brown only exists in our perception; there is no wavelength of light corresponding to the color brown.
