I can't tell a note by a color, possibly because I've never really studied music. If I had, I might be able to recognize it. But I don't know what different notes sound like, so I can't recognize them by color. When I hear a sound, I see a color in my mind's eye, usually. If the color is really strong, I may actually see it in the air. This has only happened a few times though. The most recent was the emotion thing I told you all about. 

When I read a word or letter, hear someone speak or sing, or hear instruments play, I see colors in my mind. Sometimes people's voices even have colors, but I can usually only pinpoint them if they are singing in a language I don't understand. My mind seems to put the words first. I'll see the word's colors, which will be sometimes tinged with the voice's color. (Leonard Cohen is the outlier here. Whenever I hear him sing I get an incredibly strong dark, dark grey [yes, grey with an e], flecked with bits of white, like static or salt. Occasionally, his voice will be tinted with the colors of the words he's singing.)

Fun fact: Different languages have colors, too! Spanish is all shades of yellow and orange. French is usually a mix of red, green, and blue. 

Cool!
