Chromesthesia

A type of synesthesia in which which a nonvisual stimulus causes the individual to perceive color.

Color hearing is a form of chromesthesia.

In color hearing a musical tone elicits a color.

One well-studied case involved an art teacher who had a range of consistent linkages between tone and color.

For her, high octaves tended to evoke a lighter color value, while lower octaves evoked a darker color value.

And rapid major chord tone sequences elicited rapid flashes of colors, 'somewhat like fireworks exploding.' Ref.: Haack, P.
