A spectrum is a special case of interference (pattern). When white light is sent through a prism, the mesh nature of the prism molecules create interference patterns, (alternate light and dark) but our brain perceives it as a band of colors. This is in accordance with Goethe's observations on color. He observed that colors always appeared at the boundaries of light and dark bands. (Google 'dark spectrum' for more or click the link below.)
Extending this logic we can say that color is a combination of light and dark is certain proportions. Say, 50% light and 50% dark is yellow color. Or 80% light and 20% dark is blue color. Assigning these values one can satisfy e = hv equation where blue is the most energetic and red the least. This means we get a new photon where darkness determines the color that we perceive. I call this photon a goeton where the percentage of darkness is accounted for.
If we see a red colored object, it looks red because its mesh on the surface create interference patterns. Owing to the darkness the mesh creates, a color is perceived by our brain. Therefore, the color of the object indirectly tells us about the dimensions of the mesh, it's temperature and composition. This is essentially spectroscopy.
The Double Slit experiment: The slit's edges act as a thin film and produce interference patterns that we see. This is a particle interpretation of interference.
Does anyone have any questions?
