One thing he missed in the video is the fact that red and green cone cells make up 95% of the cones in human eyes, hence our extreme sensitivity to colors that fall between the two. Dark orange looks brown because we have so much resolution in that space to work with, whereas dark green is just dark green, or dark blue is just dark blue.

He actually covers that in a previous video, the one he linked below.


In the video he said that we recognise it as brown because we learned the name for it and thus recognise it independently. Is that idea compatible with us having more red and green cone cells than blue - i.e. having more resolution to recognise brown?

Also a matter of context. Brown is orange and grey can be red.


Here's a part of a documentary talking about the cultural aspect of how we perceive colours and the power of naming a color (with the Himba people)


There is certainly a cultural aspect to it. Tom Scott's video on the matter: https://www.youtube.com/watch?v=2TtnD4jmCDQ

You could also say similar things about the secondary colors.

Dark cyan = teal.

Dark magenta = purple.

Dark yellow = olive.

And maybe some of the other tertiary colors too, but yeah orange/brown is the more prominent one.
