My favorite color is aquamarine, or maybe slightly more greenish than aquamarine, depending on which "aquamarine" you look at. Exactly how greenish I like it also seems to vary from day to day. But here's an image I've saved: https://imgur.com/a/os7tibF
I like it because it feels like/reminds me of pure freedom, on a spiritual level. Total liberation.
The song Fur Elise also feels that way to me, except for one section of it, which you can probably guess which section it is if you remember the song. You don't really get the full sense of it unless you listen to a really good rendition of it though, one by some who really understands the essence of the song. The best one I know of by far is Alfred Brendel here: https://www.youtube.com/watch?v=PtwFOOOoGlo
I know I veered from the question a bit, sue me. :D
