WebThe best natural source for deep purple and blue colors is anthocyanin. Grapes, blueberries, and cranberries owe their rich color to this organic compound. Unlike beta-carotene, anthocyanins—which form a class of similar compounds rather than a single chemical compound—are soluble in water, so they can be used to color water-based products. WebThe ‘colour’ of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws. So tomatoes are red because the pigment atoms in the skin absorb photons of all energies ... WebDefinition of Chemical Properties of Matter.
