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.

Really ? Cool, I didn’t know.
