Maybe the term "key color" is a bit confusing, after all - would you please _exactly_ define green? Perhaps "comparative intervalic excitation levels" [C.I.E.L] {i.e.-beat rates} would be better???. In ET, the only differences come by pitch level and tessatura changes, changing gradually and evenly, faster or slower as one goes up or down the scale. In HTs, or more accurately - unequal temperaments, the CIELings vary regularly, but UNevenly, as you go up or down through the scale. Key color? Like maybe, Cmaj = beige, C#min = blaze orange? The term "key color" might be confusing, but try to come up with another simile. Conrad Hoffsommer What? Me Worry? - A.E.Newman
