This was interesting. Even if a totally blind person finds out what color something is, he/she still doesn't know what it goes with. So this article causes me to envision a device with two probes on it. If you touched the probe to say an article of clothing, it would emit a musical note acording to what color it was. So if you had two articles of clothing and touched them with the probes simultaneously, if the notes harmonized, they would match, and if not, you'd know they didn't. That would be awesome. Pam
