What do the different colors of visible light represent? kinds of pigments kinds of atoms shapes of photons wavelengths of energy

The right answer is Wavelengths of energy.

White light is made up of all colors. The rainbow is actually the decomposition of white light by droplets of water like a prism.

Each color corresponds to an electromagnetic radiation of particular frequency and wavelength.

The sensitivity of the eye is maximum around 550 nm, in the yellow-green. The spectrum of visible light ranges from 400 to 780 nm but its perception depends on each individual (tastes and colors ...).
