The album cover for Pink Floyd’s Dark Side of the Moon, with white light separated through a prism into a rainbow, is a famous example of spectroscopy. The rainbow on the cover is also seen by some fans as a way to link the album with the film The Wizard of Oz—when both are played together, synchronicities seem to occur between the lyrics, music, and action on the screen.
The prism and music are linked in another way. When Isaac Newton began his prism experiments, he noted that the spectrum of colour was continuous, but separated it into 7 colours, like the 7 notes of the musical scale: red, orange, yellow, green, blue, indigo, and violet.
Spectrocop* is a typo of moderate probability on the Ballard List.
