Abstract: Systems and methods are disclosed for generating color sets based on musical concepts of pitch intervals and harmony. Color sets are derived via a music-to-hue process which analyzes musical pitch data associated with musical input to determine pitch intervals included in the music. Pitch interval angles associated with the pitch intervals are applied to a tuned hue index to identify hue note ordered within the index which are separated by a hue interval angle similar to the pitch angle associated with the analyzed pitch data. The systems and methods provide for the creation of color sets which are analogous to musical chords in that they include multiple hue notes selected based on hue interval angles derived from musical interval angles associated with the received musical input.
