Many years ago [1] I was led to a marvelous site explaining many subtleties of human color perception, including the three cone primaries. The author called this pure-M-cone response "psychedelic aquamarine"; the page is offline but the archive has a capture [2]. I haven't seen this color referred to by that name elsewhere, but I think it's a good name.

I think I can see psychedelic aquamarine and the other cone primaries by closing my eyes and rubbing my eyelids while pressing in gently but firmly.
