Brown is on the colour spectrum, it does have a wavelength. Specifically, it has the same wavelength as orange. Because brown is dark orange and orange is light brown.
What’s not on the colour spectrum are multi-wavelength mixed colours like e.g. red and blue light combining to something that looks like spectral violet. And while these multi-wavelength colours are physically different than a pure spectral colour, the sensation to a human is identical, because both trigger the cone cells in the eyes in an identical way. Which is why we can have screens that only emit three colours and still trigger the same sensations as millions of different spectral colours.
I can’t find the wavelength online, can you tell me what wavelength brown is exactly ? By that I mean any specific length that if a light source only emits that wavelength would be brown.
The difference between brown and orange is the brightness level, and since the eyes have an automatic brightness adjustment, brightness levels only appear in context.
Light becomes a darker variant if there’s brighter light around and vice versa. Shine brown/orange light into a dark room, and it will appear orange. Shine the same light into a brighter context, and it will be brown.
It’s exactly the same thing as e.g. dark blue or light blue. Both share the exact same wavelength, and their brightness becomes apparent in context.
If you’ve ever been to a cinema and you saw anything brown or orange on screen, you have seen the effect. If you have ever seen a dim conventional light bulb in a bright room, you have seen it too.
Brown has just as much a wave length as orange, because it’s the same color.
Brown is not in the color spectrum, doesn’t have a wavelength, yet we can imagine it and see it.
Space is a finite number (three) of dimensions, yet we can imagine space with higher number of dimensions.

Really ? Cool, I didn’t know.

590-620nm. Identical to orange.

Yup technically orange
Also magenta. Actually, white and black too.
