  • Red, though? Blood. The colour might vary a bit, but nowhere as much. Black? Soot. White? Clouds, chalk. It’s simply easier to generate points of reference for those.

    Too true and makes sense, but what confuses and vexes me is the idea that “yellow” would predate “blue”: Blue things include bodies of water and the sky (assuming the azure/cyan and royal blue/standard blue are the same color), but what important thing is there that is yellow that we need to talk about so urgently? Blue comes up with some foods, but it is rare and other natural phenomena like colors of a night sky, but I’m struggling to think of the reason why we needed “yellow” prior to that. Any conjecture?

















  • There is still a meaningful distinction between spectral and non-spectral colors as far as I (a non-scientist) is concerned: what one is saying is “this is my perception of a specific wavelength of electromagnetic radiation” and non-spectral colors are “this is my perception of some kind of weird interference between opposing colors or a bizarre trick of the brain or whatever”. Color as such is still a purely mental phenomenon but what instigates that phenomenon can be different.


  • Because you are responding to the post itself without reading the post. You have nothing to add if you’re fundamentally ignorant of what the source is. You may have something meaningful to add in response to another comment, but this is no different than saying "I didn’t watch this movie, but here’s what I think!’ or not doing the reading in a book club and just showing up to throw out random conjecture.
