I'm gonna take this chart and use it with my blind friends. I wonder if a single note represents color or is a combination. "Feelings", are most likely a part of it. A few years ago, my agent had me get out of a car and he wanted me to see what a daisy looked like. It was in the early morning so the dew was still on the flower. He had me take a breath mint and breath in. It was cool, and he said as I touched the petal, that is white. Then he had me touch the middle of the flower where it was yellow. He said, "Put your face to the sun, and feel the warmth on your face. That is yellow. When I breathed in, and felt the cool in my throat and added the warmth of my face of the yellow, it kinda made sense to me. That's where we thought if we added music, we could see color.
