These ratios seem to correspond to the photoreceptors in the human retina, which are sensitive to wavelengths of light in three different ranges: long, medium, and short.

- The musical circle of fifths, derived from these simple proportions, - can be studied in more detail in this program's Pythagorean scale - mode. Similar notes can be found by color and compared. One can easily - hear how stacked fifths overshoot the octave by finding two far-apart - red notes and playing both at once, which makes them beat against each - other.
