Recently, I was sitting in my car listening to music, and it got to a part in the song that I usually really like, and usually think sounds very green. Only this time it was kind of unpleasant and yellow. I immediately determined that this was because I was feeling a little nauseated; nausea is high-pitched and yellow, and this part of the song was similarly high-pitched, so the unpleasant yellow was bleeding through over that frequency.

Then I thought that this was probably not a very normal thought to have.
