  Riddle me this: if there’s no such thing as brown light, how do you see the color brown on your phone screen?

    There isn’t a specific wavelength for the color “brown” (non-spectral color), unlike the primary spectral colors such as red (between 620 to 750nm), green (520 to 570nm) or blue (450 to 495nm).

    What we perceive as brown will often been a combination of red and orange (590 to 620nm) wavelengths with a reduced intensity. On an non-HDR monitor, which uses RGB pixels with 255-levels of intensity, it could be represented as R=77, G=27, B=00.

      Grouped tightly enough, this combination of red and green wavelengths will provide a perception of the color we call “brown”

      If you defined “brown,” you’d have to do it that way - by describing the wavelengths that we perceived as that color. The fact that your phone screen - a technology that works by emitting light - can display brown means there’s light that we call “brown.” It may happen that is really a dark orange, in much the same way that pink is a light red, but so what? It’s light and we see it as brown. Brown light.

    Get a Philips color changing bulb. Open the app- Find brown.

    Case rested.

    I never said brown as a COLOR. doesn’t exist. I said brown LIGHT doesn’t. Your argument could have been the Sam if you said “Why do I see brown colors on TV?”

    Go look it up. Science is with me on this.

      I get what you’re saying, but color is weird. There’s a specific term to describe colors that come from light sources, and colors that are a result of an object absorbing light.

      Don’t take my image too seriously, it’s incredibly cherry-picked and not meant to serve as some sort of debate point. Although it does look like a very light shade of brown IRL…

        I get what you’re saying, but that’s the stealing yellow light on a brown or tan surface. What I mean is:

        Imagine a laser light. Now imagine one colored brown. You can’t. But orange, purple, green, etc… all can cast light. Brown cannot.

    By it emitting orange light (or the combination of rgb lights that add up to orange anyway), but only a little bit of it compared to what it would do if you wanted it to actually display orange.
