Brown is actually dark orange. It just became its own thing when we gave it a distinct name. So people who know more color names really can see more colors.

darker than what? There is no such thing as dark light, colors like brown and pink that are lighter or darker require a comparison point to see

lighted-display (like a monitor or TV) of brown is dark orange, yes.

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.

No it's not. Orangey-brown is kinda dark orange I guess, but greenish brown is certainly not

[–] Acinonyx@lemmy.sdf.org 7 points 16 hours ago (1 children)

what's the hexcode for greenish brown?

It doesn't exist. Nor does brown. It's all just orange, but with extra context. Here is a video you should watch that will be exploring the color brown.

I can smell a Technology Connections link from a mile away, apparently.
