>>14056669Visible light has frequencies ranging from about 430 to 750 THz. If you scale the frequencies you can get *almost* a full octave in the visible spectrum (F and F# probably both get cut out):
G would be a deep dark red.
A would be a bright red.
B would be a yellow green
C would be a vibrant green
D would be a deep blue.
E would be a light violet
F would be deep deep violet pushing the limit of visibility.
