I like the use of base 12, but IMO it's somewhat wasted on a diatonic staff. This is basically just traditional notation with special coloring to make it easier to read. To better match the keyboard, I'd rather use an isomorphic staff (a.k.a. "chromatic staff", although I dislike that name because it implies diatonic music as a default).

There's a web site you might be interested in with many examples of isomorphic notation at:

Wow, I wish I had this when I learned to play. Keys, clefs, and accidentals felt like a hazing ritual, completely accidental (hah!) complexity. I always hated that I couldn't read the treble instrument parts at sight-reading speed simply because the sheet music used a different clef.
