An absolute memory of 12 colors corresponds to an absolute memory of
pitch for 12 categories spanning the entire range of audible frequencies
from 20-16.000 Hz (at my age). I suppose this can be learned in a few
minutes. A hemitonic absolute pitch memory covering a musical relevant
range of frequencies would correspond to an absolute memory of roughly
90 color shades (only hue, same saturation and brightness).
