Hm, I don't really remember. I think I talked with friends about how letter & numbers have colors and they didn't see it like that. Well, I wasn't too surprised about that. I was more surprised when I found out that it has a name.

Btw, songs have colors too. I think most of the time they get their colors from their titles. But sometimes they get it from the vision I get from them. Sing for Absolution was a blue song once. When I saw the video, the song's color changed to yellow. I like it much better as a yellow song.
