I've had two meals involving ketchup today.
I need to start eating better, yeesh...

Synesthesia

Well color me surprised. When listening to music I often close my eyes and just let my subconscious conjure images and (more often than not) colors. I have an inkling that this is why I respond so strongly to Rothko. I always loved that about myself, that I could make an internal lightshow out of anything. I have described it to friends as "watching my subconscious." I didn't realize that this had a proper name. I don't put too much stock in it, but it is fascinating to think that other people see the same sort of things I do. (The following is from wikipedia)

Music → color synesthesia

In music → color synesthesia, individuals experience colors in response to tones or other aspects of musical stimuli (e.g., timbre or key). Like grapheme → color synesthesia, there is rarely agreement amongst synesthetes that a given tone will be a certain color, but individuals are internally consistent. Tested months later, synesthetes will report the same experiences as they had previously reported.

Color changes in response to pitch may involve more than just the hue of the color. Brightness (the amount of white in a color; as brightness is removed from red, for example, it fades into a brown and finally to black), saturation (the intensity of the color; firetruck red and sky blue are highly saturated, while grays, white, and black are unsaturated), and hue may all be affected to varying degrees (Campen & Froger 2003). Additionally, music → color synesthetes, unlike grapheme → color synesthetes, often report that the colors move, or stream into and out of their field of view.
