A Musical Symphony has Colour ... in the Physical Sense of Musically expressed "Sentiments" ... felt as, Audible Vibrations, of varying Intensity.
Similarly, Colour has Sound, in the Physically Sensed, Photonic Vibrations ... these are "Emotional Stimulation" of varying Intensities.
Both, Sound and Colours, are Distinct Human Awarenesses ... one has to do with the Audio-Optical and the other, with Audio-Sensual Sensing of the Phenomenon.
Sound and Colour can be "Physically Measured" in the "Relative Sense" ... Though, in the present Sense, the Ultra-Violet Radiations related Vibrations will require to be Redefined, as the "Ante-Violet" Sense.
In "The Law" Governing Natural phenomena, both Light and Sound are Composed of Distinct set of Vibrations that makes them Unique.
